I wish Sony would make their controllers bigger, or at least offer an official aftermarket larger controller size, or at least longer handles
Currently I much prefer the XBox controller, despite the lower functionality, as even though it's still a bit small, it ergonomics do allow it to fit my hands OK. With the Sony controller I find that I can't use it for that long as I'm contorting my hands to get to all of the required buttons.
Funnily enough if you put the XBox and the Sony controllers together there doesn't seem to be a great difference in size, but as it stands on the Sony controller the L/R buttons/triggers fall directly under the first knuckle of my middle and fore fingers, which is not comfortable. With the Xbox controller my fingers seem to naturally fall into the right place.
