I've played Live in consoles all my life, until last year. I decided in Feb 2005 to buy Live 2005 for PC (I already had it for Game Cube, but it was so choppy) and it really was a great decision. I mean, I always tried to have updated rosters and players with their real accessories, but in the console I was very limited.
My suggestion is if you are not obsessed with rosters and accesories of the game, buy the game for the console, because it's more confortable, and you don't have typical windows crashes (well, I never had them, but I know some people who did), you can play with some controlers on a sofa in a big TV screen. Buy only the PC version if you're a daily NBA fan and you have a good two-analogs joypad.
That's all, I hope I can help you
