Both are certainly at the top of the future of pool for sure. One pocket seems to take most great players at rotation, about 5 to 7 years at least, to really be top level. These guys are both smart enough and shoot well enough to beat anyone on a given day, but there is no substitute for being in the trenches with the monsters of the game, and learning how to deal with all the main styles. I believe that is why they have such a hard time with Tony , nobody that I know of ,ever played like he does, and won. It must be very disconcerting to play a great safe and have him run out on you , then do it again 3 games later,with the same result. Between Gorst and Filler ,I believe Filler has the most potential at one pocket , imo he has better instincts, whatever that means. I guess he just seems more comfortable with the game.
