Im mainly talking about sidequests. I found oblivions to be extremely bland. Skyrim has plenty of awesome and memorable sidequests that i thought they did a great job. i love the forsworn conspiracy, A night to remember, Everyone of the daedric quests(especially a daedras best friend and boethias calling). I can see people liking the guilds of oblivion more due to them being longer. The dark brotherhood from oblivion was my favorite questline out of either game. For the most part though i enjoy the quests in skyrim a decent amount more than oblivions

I'd say they are about on Par. The thing that sets Skyrim ahead of Oblivion for me in the quest stakes, has to be that the majority of caves, ruins etc.. have some sort of story to them. Where as OB didnt really have much back story as to why Bandits were here or there etc... reading journals about their activities etc.. is very enjoyable.

They did well on some of the side quests but oblivion had as well. I actually prefer the daedric quests in oblivion because a good bit of them I was effecting communitys and such. They seemed a bit grander so to say. I like yhe mq in skyrim over the oblivion on sole fact of the oblivion gates lol. I keep thinling about some side quests in oblivion that had me going all over and having to track down info and I had alot of fun with them. The side quests in skyrim were fun just needed to be a bit longer and a bit more thought provoking instead of the usually just go here grab or kill whatever and then ur done. Now that isnt all of them but its a good majority of them.

I prefer Oblivion's. Having said that, I do enjoy most of the quests Skyrim has to offer.

there are a few good ones in skyrim, but, i liked a lot more of the guild and sides in oblivion, by far.

I haven't done all of Skyrim's side quests yet but the ones I've done so far were more interesting to me than Oblivion's side quests.

Skyrim's quests don't interest me much. I mostly treat the game as a dungeon crawler these days. It would be great if there were more quests with branching outcomes, it would add so much replayability to the game.

I like oblivions replay value more then skyrims because in oblivion i like the guild quest, main story, and side quest better. I haven't done a lot of the daedric quest in oblivion so i cant say which one i like better.

Honestly, about even. I liked Oblivion's MQ but it could of been better. Skyrim's MQ was pretty good IMHO.

This.
Some additional comments:
Skyrim quests have an annoying habit of 'interfering' with each other at times. It seems to me that if quests 'cross over', there ought to be a way of preventing one from being active while you execute the other; or, the dungeon/cave/ruin should immediately RESET once you finish a quest and the subsequent quest uses that same 'facility.'

I thought the smaller side quests in Skyrim to be generally superior to the "chance discovery" type quests in Oblivion. Particularly liked the Gauldur legacy episodes ! ( It should not have required Mages Guild to complete it tho...) They could have thrown a few more like this in, A + B+ C + finale = big payoff. The daedric quests are on a par with Oblivions, though I really wish so many hadn't been so "evil" ala "kill the quest giver, kill a friend" toned. Personal preference, I know many thought Oblivion to not be "Dark" enough.

Oblivion had the better central (main) quests IMO. The main quest in Skyrim is good, at least equal to Oblivions.

The ending in Sovyngarde is OK, but that last battle... mmm, pretty weak! My only complaint was the Blades not really accepting my judgement. Kill one of the best and most intriguing characters in the game, or you don't get to play with us was not a well thought out idea...... Understand the "you make hard choices" intent, but it seems not to fit with the game, being as it is more linear model than in Oblivion.

The rest of the quests though... too short, and too simple in execution.

Mages quest, some great locations to visit, Labrynthian was superb, but no way do you really earn your stripes to become head mage.

Companions / Fighters . Biggest let down in the game. Way too short.. and the Werewolves thing seemed totaly misplaced. ( It should have been an entirely different "branch" quest line. I'm not certain if Bethesda even planned them to be joined at the waist originally.... I suspect it was probably done to expedite game completion by 11/11/11. I liked the character of Kodlak, but the pacing of the questline totally sabatoges the development of a sense of connection. The funeral pyre scene is written decently, but everyone stands around woodenly, and there is no emotion. Sadly the soundtrack appears to have been toned down here as well, I think it was meant to have a solo violin accompanient layed over it that really pulled sadness to the fore-front, but it somehow got buried beneath the vocal dirge. As for the Silver Hands, their lack of a distinctive leader, relegates them to being little more than a more vicious type of generic bandits.

Dark Brotherhood? Can't quantify this truthfully. Oblivions was pretty good, though I roleplayed and finished killing off all those sickos but the Nightmother (couldn't touch her!) after its completion. In Skyrim, I've justed waisted them, rather than join up, I get annoyed at being targeted by them so early in the game.

Thieves Guild. Some good hand written jobs, mixed in with a ton of RGQs ( random generated quests). Vastly inferior to the questline in Oblivion. It was interesting initially, had great fun sneaking around the honeyfarm on the island, but nothing afterwards really seemed to build up as well. Mercer Frey was not written well, he seemed far too hands on to be a criminal mastermind. And like
the companions, tacking on a seperate Daedric side element , seemed pretty cheap, and contrived.

In conclusion, with the way the RGQs didn't work out, I just wish they'd dumped them when they realized the game suffered from them, rather than tried to rescue the questlines, with a hodge podge mix. I think Bethesda has the talent on hand to write some very good adventures, but for whatever reasons chose to gimp themselves. I Hope they learned their lesson with this, and that Fallout and other ES titles will be given enough budgetary money and time to bring back the depth of story which made their earlier games so enjoyable. We'll see if this happens with the DLC I guess.....

There are a couple of good side quests in Skyrim but I don't think there are more memorable ones than in Oblivion.

Then again my mind is clouded by all the horrible quests from Skyrim's guilds. They were incredibly bland. Often you can tell that there was a good idea behind it but that it was lost in the execution. Even worse is that there are only a few quests in each guild so my memory of Skyrim's guilds is all bad and as a result I don't remember quests in Skyrim as a good thing.

I'm generally more about the sandbox elements than the actual quests. To me once you've gone through a quest in one play through you've pretty much gotten all the enjoyment you're going to get out of it. Future play throughs I just try to get through them as quickly as possible to get the reward.

That being said, Skyrim does offer more options on how to complete quests than Oblivion, although there's still plenty of room for improvement. It pissed me off during the Thalmor estate thing that I'd throw my voice with a shout (pretty much the one time in the game that that shout would have been useful) and they all completely ignore it. Like I'm just supposed to run through there slicing and dicing everything instead of sneaking through like I wanted to. But an interesting twist was I helped out one of the lesser jarl's before starting that quest, and that jarl just happened to be at the party and that jarl just happened to be willing to help me out a bit. I don't remember anything like that ever happening in Oblivion.

At least you earn what you get in oblivion through long arduous quests and battles. Becoming archmage in skyrim=less than 10 quests of retrieval work that the other mages are too lazy to do, archmage in oblivion=uncovering a powerful necro cult devoted to an ancient bad@ss, learning new magic, and finally slaughtering 100s of mages and zombies to earn your place.
Multiple daedric quests had you going to isolated parts of oblivion in oblivion and though skyrim has decent daedra quests it does not mean anything without the realm being visible.

I liked the journal in Oblivion over Skyrims interface. Thats about it. Though, I did find allot of the quests, side and mainline, more appealing and more fun, in Oblivion.

I think the side quests in Oblivion had more variation and creativity.

I liked Oblivion more than Skyrim tbh so shrug. I actually consistently played Oblivion till I beat it. I stopped playing Skyrim altogether and have never beat the main, civil war or DB questlines as well as not exploring most of the maps. It is because of the quests. They are exhaustive and boring with no intellectual challenge because of the quest markers. If you take those off you do not have enough clues to even figure out the quest because they relied WAY too much on the quest markers when making the quests. I also think Oblivions faction quests were much better than the ones in Skyrim. Mages guild>College of Winterhold, Fighters Guild>Companions, Thieves guild(Obl)>Thieves Guild(Sky). There are very very very few noticeable effects of pretty much anything you do in Skyrim imo. Choice has no meaning. 80% of NPCs are essential and that is effing annoying!

I would say Skyrim has some pretty well done Daedric and misc quests or random stories in a dungeon with some background.
