You need to look at the exclusives of the system and determine whether you like those kinda games.
Xbox 360 has a ton of quality exclusives though:
Forza series
Fable series
Halo series
Gears series
And then there are quite a few other exclusive games that you might want to look into like Alan Wake, Crackdown, and quite a few xbox live games.
So yeah if you think you going to get into the games and franchises i mentioned above then absolutely get it.
