For the 7th generation, PS3 all the way. I find the controller pretty comfortable to hold and use. Plus it still has a fair number of great exclusive games (Uncharted, Resistance, inFamous, Killzone, etc...) Of all time... It's a toss up between PS2 and SNES. Both had great libraries of games.
Ps3, I had a XBox 360 for a while switched to the Ps3 a couple years ago and Ps3 is just much much better in my opinion...
