NBA Live 10 or NBA 2K10 which on should you get and why?

Nba Live is more challenging when you're playing online or by yourself but, NBA 2k10 is more challenging in a new mode called 'My player'. Personaly i prefer Nba 2k10 because NBA live gets boring after about 1-2monthes. If you like to cheat against your friends on nba 2K10, then, that's the game for you.
