for me symetrical.
As my body and my hands are symetrical.(hope my english will be good enough to explain)
My problem with asymetrical is the diagonal position of the left stick.
With an n64 controller your thumb goes straight up-you can move up/down/left/right without problems.
the same with the playstation controller-the thumb goes pretty straight to the right.
with the xbox controller the left stick goes diagonal,therefore my thumb goes diagonal and I have to compensate the radius of my thumb joint more than with the other controllers-especially when i move from left right my thumb often moves diagonal to the left upper side instead straight left.
