I think some of the NBA live 09 look better than NBA 2k9, but 2k9 is the winner here. I think most of the Live models makes them look like raptiles. When I played the demo, Kobe reminded me of the raptor scene from Jurassic Park. I chose 2k9 although I had 2k8 last year. NBA 09 is pure garbage and didnt even come close to being a contender in my mind.
