To be fair, a better comparison would be 2017 Wolford vs. 2019 Hinton, right?
The big difference to me between these to QB's is speed in the mid-range route game. Sure, Hinton's more elusive than Wolford, but not by all that much and their general speed is about the same. In his few appearances this year Hinton also looked a little bigger and less like Dortch playing QB, as he did when he was a freshman. While Hinton throws a stronger deep ball, Wolford had a much, much quicker release. His decision making was also seconds quicker than Hinton. Those are VERY hard jumps to make. Wolford made the decision-making jump his senior year, but already had a quick release and a good arm.
I think that's where the 2018 Hinton will struggle to keep up with Wolford, but the receivers are going to be awesome. Offensive line should be better, running game should be as good if not better. Schedule will be a little easier.
My guess is that he won't get near the point total or gaudy numbers of Wolford this year, but we'll still get one more win. Then 2019 we'll be a dark horse ACC title contender as he makes the senior year leap. Hopefully it'll line up with a year where FSU/Clemson aren't juggernauts.
