I grew up with the ps dualshocks from the ps1 days & the ps2/ps3.
I always thought they were great but when I bought a 360 the offset sticks took literally an hour to get used to - then you realise that they're actually more comfortable than the Sony pads & make more sense - because of where your right hand sits you can reach the right stick & all the buttons without shifting your hand - there is a lot less fatigue on long gaming sessions for me with the 360 controller.
The other benefit is , with it being an ms product it has 100% native support for all gamepad compatible titles.
