I'm a little late to the topic. But I want to post it anyway.
Right there with ya'll 'bout Brynjolf and Ulfric. I'm also one of those people who likes Cicero. And Teldryn Sero, if you can get his helmet off. And all my characters, in an un-modded game, end up with Vilkas. I also hate the Thalmor, but can't resist them in those robes. Mainly Ondolemar.
When I was a teen I had my walls covered in pictures of Dante from Devil May Cry. I probably still would if it wouldn't bother the husband too much. And Sieg Wahrheit from Chaos Legion.
I'm a Garrus-mancer, but I still mightily appreciate that Kaidan squeezy squeezy.
Alistair and Anders usually for me, which is not to say I lack appreciation for most, if not all, the others you've mentioned.
Ezio!! All his games are what got me into AC in the first place.
"FBI Special Agent Francis York Morgan. Please, call me York. That's what everyone calls me." Deadly Premonition.
I could probably go on and on. I'm starting to think I just play games to leer at people.
And I didn't mention Cullen. Because that should pretty much go without saying.
