Based on what you like, I would go for the 360 Premium.
Make sure its the newer models and look for a bundle.
The only reason I would consider the PS3 is you already have an HDTV and are also interested in buying/renting bluray movies. Then the additional $ for the PS3 is ok. Keeping in mind you are losing rpg's and a generally better selection of multiplatform games.
but, that's just my opinion.
