Just my one sided qvasi comparative and offtopic unspellchecked comment on the rumbleless controller of the PS3:
I like the fact that it is small and light , even though I have big hands. I hold it loosely, easily shifting it around to get to the different buttons and such. I do have problems with some button combinations, I think KZ2 comes to mind. If the xbox360 controller would fare better in those situations, then it would get a pluss. The handles of the xbox controller fit better in your palm yes, but I don't grip the controller tightly, so that's less of a factor for the PS3 controller.
It does not feel more fragile at all, it is just lighter. I twisted an xbox360 controller once to get a feel for the robustness, and, compensatingfor my bias through logic, I would say that they are the same.
The convex sticks are logical, offering the same contact caracteristics no matter how you roll your finger around on it. Sticking your thumbs into dips, thus having to bend the thumb sounds pretty unconfortable to me. I wouldn't do that.
I like to slide my fingers off the R2 and L2 triggers. Requires less effrot than lifting or letting go I think.
I like the fact that it is cromatically coherent.
I like simetry.
