Sorry, man. I just found your response to me from quite a while back.
As far as the PS3 and 360's GPU's, they are essentially equal, on paper. But, the PS3's very strange CELL processor can actually act as more GPU power. It's a very fascinating architecture, to say the least.
Plus, the GPU is just one factor. The PS3 crushes the 360 in terms of processing, features, etc. It is also much more reliable, but I don't think I need to go there. Ha! Ha!
And, while more enemies on screen, better graphics, better sound, etc. don't define a game as good or bad, you'd have to be kidding me if you actually think it doesn't heighten the gaming experience.
Just imagine what KH3 could be like with the full 50GB of Blu-ray. Plus, by that time we will be using 100GB Blu-ray discs, at the very least. Recently, it was announced that the new 400GB Blu-ray disc will work on the PS3.
I hope that helps!
