Only one good way, What ever is comfortable to you! The only thing that matters is that the ball goes in the hole. I say practice a bunch of them.

I recently was struggling with the flat stick ( 10 ft and in) so I just switched between grips every round I played. I found the one the grip that works best for me and gives me the most confidence. It is very similar to a "claw" grip only my left hand is turned Palm up.
