For me it is either the gamecube controller or the 360 one.
The gamecube controller has a little better grip then the 360 one but lack that little extra weight I want. It feels kinda cheap. The analogs are also to sensitive.

the analogs on which controller because you can turn your sensitivity up and down on your 360 you just need to snoop around in the system settings and console settings to find what your after but if ur gna do that i advise watching a tutorial first.

Comfiest Controller Ever

I would have to say xbox 360 controller

i like the 360 and PS controllers. they are very similar, they both have four face buttons both have two analog sticks which double as buttons and a D-pad they're just switched around, they both have shoulder buttons only their shape is different, both have a start and select.

they are also both very comfy
