Go rent them first if your stuck on your decision. All games are repetitive...not sure why reviewers keep harping on AC about that as a such a big downside?
I'll go out and say Mass Effect. Bioware puts out some amazing games and their story-telling continues to improve more and more. If you're not a big online player, this is a better way to go. Lots of hours for single player in this game.
