Wiimote, I feel most comfortable using that particular controller. I like the extra immersion it offers. Makes me feel more involved.

I like how the Sixaxis is so light. Now if it only felt more reliable since my buttons are sticking, my analog stick is messed up, and it cuts out sometimes.

SNES FTW

There was an article posted here on Vgchartz a while back where multi console owners (PS3 and 360) owners where questioned about different aspects of their consoles. One topic posted was their favourite controller.

The PS3 controller got 6 votes, the 360 controller got 5 votes.

That survey may not be perfect, but it's about as unbiased a source as you're going to get.

In my opinion the 360 controller is far better than the sixaxis. I have no idea though how the dual shock 3 controller stacks up but it does fix two major problems I have with the sixaxis, lack of rumble and being too light.
