It's going to depend on what games you like to play. Remember, the purpose of a game console is to play games. if it doesn't play the games you want, you've basically just bought a fancy dust collector.
PS3 
Wii?
Xbox 360
You could look up what kind of games you like and see what consoles they come in, then choose based off which ones have the most games that you like.
Xbox 360 or PlayStation 3 with sharp shooter and killzone 3
