My girlfriend and kid sister hated the XBox 360 controller (too bulky -> cramps), I didn't hate it but certainly prefer the PS3 controller. I like to have the analog sticks next to each other, I can't imagine being within the top 0.1% highscores if I played Super Stardust HD with the 360 controller.
I hated changing and charging the batteries, just using a USB cable connected to my PC or PS3 while still playing is IMO far more comforable. Imagine having 3-4 controllers, what a drag...
