Funny - when I was configuring what I would like I debated this. The wheel on my GT350 is alcantara and frankly I preferred the feel of the leather on my SS. Plus I am not that wild about the look of alcantara on control surfaces - elsewhere is fine. No doubt the alcantara is grippier but I just prefer the look and feel of leather. So unless you are going to be a track rat, I’d say go with your preference.
