What is the best 2h weapon in the game? Is it just Daedric with enchants? Or is there a unique weapon?

What about axe vs sword vs mace?

I never had a reason to consciously use 2handed weapons. I have three playthroughs: a sword-shield tank, two-daggers illusionist vampire, and a hand-to-hand werewolf.
That said, The ebony blade is my favorite two handed weapon, because it uses one handed perks.

Mace = Slower attack speed but higher chance to stagger
Axe = Faster attack speed with a decent chance to stagger
Sword = Fastest attack speed with a low chance to stagger

I think thats about right

I prefer Daedric Battleaxe personally Very big, very bloody..

Ebony Battleaxe in my opinion. And speaking of "awesome" 2h's, it svcks that the Battleaxe you get from Clavicus Vile is so crappy. I mean what the hell, just 200 years ago he gives away Umbra and now its that P.O.S.??

I used http://www.uesp.net/wiki/Skyrim:Volendrung and http://www.uesp.net/wiki/Skyrim:Wuuthrad the most with my two-handed warrior character.

Volendrung absorbs 50 stamina with each blow; however, Wuuthrad can make use of the Elemental Fury shout.

2-handed, 1-handed sword & shield, 1-handed dual wield are all very different playing styles. It's fun to try each of them with different characters.

I wish Wuuthrad wasn't so weak - It should automatically be Legendary+ quality.

Wuuthrad, awesome for killing those damn witch-elf's ( referring to the thalmor and most of the hypocrite dunmer in windhelm)

I like Volendrung. Best I've found so far.

Personally, I like Claymores since they have the quickest ATK speed compared to the others. My tops?:

1. Daedric Greatsword
2. Ruefel Axe (It's pretty, you can improve it unlike the Headsman's Axe/Wuuthrad, and it has a decent effect. 20 pts of Stamina DMG)
3. Ancient Nord Hero Battleaxe/Greatsword (They might be technically "Steel", but they've always done the job effectively)

Other then that? Ebony Blade jus cause it's a BA 2H Katana.. and it's pretty! ^.^

Im on my first play through. Currently dealing death with a Daedric Greatsword.

My Wizard loves Two Handed Swords. From purely a vanity perspective, I am upset that when my Wizard casts spells, the Sword is not strapped across my back like it was in Oblivion. I liked how that looked.

My Orc Warrior has only disdain for any weapon that is not a 2H Hammer.

Honed Ancient Nord greatsword, from red eagle.
It surpasses ebony greatsword if refined. I have yet unlocked daedric so the honed gs is the best.
Besides, one full refill of the enchantment charges = 1 common gem. No need to waste grand gems, and u have about 150 swings. One of the best greatswords in the game

Agreed.

If you are using smithing exploits, it's possible to make something with higher base damage, but I really enjoyed Volendrung. Especially combined with the 2H perks that allow warhammers to ignore enemy armor.

I also used Wuuthrad quite a bit, especially when fighting Thalmor agents.

I am favored to Daedric Greatswords. Well, greatswords in general. I opt for the faster swing over the extra damage. And I like the way they set low on the back of my char. Axes and hammers tower above the char.
