Sorry guys, but I find it very very unlikely that you've played both Fallouts and Skyrim and suffered no issues worth mentioning. No broken quests? No missing NPCs? No corrupted cell areas? No items forever stuck in your inventory? No hardlocks or crashes that need you to switch off the console?
Crashes, yes of course. But they usually just occur after playing for 6 hours.
A simple restart and back to normal. (I'd say that's the consoles problem, not the game)
I've only had two corrupt auto-saves on Fallout: NV, but otherwise never had one with a Bethesda game. (not even 10 years of Morrowind)
No broken quests come to mind.... at all. (well, ok, maybe some in Morrowind.... but they were small matters, and didn't "break" anything important)
I finished the Skyrim Thieves Guild and http://www.uesp.net/wiki/Skyrim:Blood_on_the_Ice with no problems, while everyone else was crying about how "broken" they were. (before patches even)
I really feel like Skyrim is the most bug-free Bethesda game, and Oblivion and FO3 felt very solid too.
I am not saying these problems do not exist, I've just never really experienced anything that actually caused problems.
I'm not really counting Graphical bug/glitches, because all games have a few, and often do not repeat themselves in a harmful manner.
