Why should i keep my ps3?

i just got it today and it doesnt seem worth it. i got rsistance and the ps3 controller sucks for fps i miss halo 3 but my 360 is being repaired. i see no reason to keep it since there are few exclusives like ratchet and clank sounds cool i never liked the unreal series and haze is a fps and the controller is so uncomfortable to play them. im thinking i will return it and maybe(its less likley since this experience) buy a ps3 when it has a dual shock 3 and mgs 4 comes. maybe someone can convince other wise or give me more reason to return it.
