i dont know, i have both live 08 and 2k8 and live is the superior title by far
I struggled playing the game. There is just to much emphasis put on offense that it becomes unplayable for me, and that isn't just my opinion on it. I've heard from others and read in reviews that say the same thing in regards to it being more offensively focused. Live takes more of a casual approach to the game, and the casual NBA fan probably enjoys dunking every time down court but for me it just gets boring. That said just go with what you enjoy. I enjoy 2K8 because you can run an effective offense/defense and change your teams style of play (Offensive tempo, fast break frequency, steal tendencies, close out speed, contest shot or go for the board/break, etc.) to suit your personal. It may be more of a nerdy NBA game, but the realism of it appeals to me and makes it much more enjoyable.
