One thing I've realized with V is that since you have so much air control, keyboard is superior. You have different buttons for lean back and turn, making you able to perform both to a greater extent at the same time. With a controller, you pull the stick diagonally, reducing how much of each you can do. Gaining speed while doing a wheelie and being able to turn makes maintaining speed a lot easier as well.
I keyboard stunted VC for the control but GTA:V offers so much more air control that I think if air becomes more technical, keyboard will really take the cake here.
