If we are not talking exclusives only then the 360 has the best chance as it shares many games with the PC. And I'm not just talking about games Microsoft is some how involved in like GeOW and Mass Effect but also games from relatively unknown developers and publishers who dont have the time, money or expertise to make a PS3 version. Usually those games wont reach a 90% average but some might.
