I have 2 super's and 2 360's. I use the P360's for player 1+2 and the super's for 3+4. When using them, they both feel very similar, but there are some differences that make me like the 360 better.
The 360 feels smoother when in motion, especially a circular motion. Also, the corners of the P360 are harder to hit.
I am not entirely sure about the restrictor plate, but I would guess that the restrictor plate would be just fine with either type of stick.
