PS3 for the BluRay player alone. It looks fantastic on my 55" Sony HDTV. If there is a single game out there to make me choose, it would be Final Fantasy XIII which just arrived in the mail yesterday. Its stunning in 1080p and the game fits onto one single BluRay disk.

The 360 version of FFXIII comes on multiple DVDs you need to change out and the graphic quality is very poor. Its basically been converted and compressed, which kills quality and is run at 720p only.

You can see side by side screenshots if you Google. 360 version has many choppy lines and just didnt hold up to compression very well in the FMV portions.
