Should i trade my xbox 360 for a ps3?

Hi, i own an xbox 360 and i have been quite happy with it, but recently i went to my godparent's house and played ps3. the ps3 had exellent graphics and my cousins and i had a ball playing time crisis and ratchet and clank tools of destruction. ps3 can also play blu ray. should i trade my xbox 360 or should i not?
