Only played the trilogy. And would put them in this order:
2
1
3
Thought the second one had the greatest set pieces and art style. And some great new mechanics and the best boss fights (might be tied to 3 in this regard)
The first one was also amazing for it's story and inventiveness.
The third one is amazing as well, but kind of pushed everything to eleven. A little too violent and epic. But certainly some amazing puzzles, boss fights and set pieces. Disappointing graphics in my opinion. It looks fine, but doesn't really push the ps3
