I would like to get one of these games, but which one is better?

I hear that Oblivion feels more alive, but the graphics are strange.

Skyrim has better graphics and the fighting style is better, but feels less alive.

Compared to SW KOTOR 1&2, what is the level of "sexual content"? I don't want to play a game that makes you get into that stuff. If it is an "choice thing" and I don't have to see or hear that stuff, that will be good.

Please, I would like to hear multiple opinions on this.

Which one over all is the best?
