The enormous majority of sports games are multiplat.
However, I know that MLB: The Show (baseball) is a PS3 exclusive series (07, 08, 09 so far). Don't think the 360 has any exclusive sports games at the moment (it does, however, have an open world snowboarding game coming up soon).
Football: Pro Evo is best, multi.
Hockey: NHL ** is best, multi
Basketball: NBA 2K and NBA Live are multi.
Golf: Tiger Woods is multi
American Football: Madden is multi
Boxing: Fight Night is multi.
Baseball: MLB The Show is PS3 exclusive, and far superior to MLB 2K, which is multi.
