I think Bama wins the most in the next 10 years because your recruiting/development has been the most consistent. My prediction is Saban coaches at least another 3 seasons and your transition to your next coach goes smoothly because, in addition to the abundance of talent, I think Saban has instilled a culture that will carry over almost no matter who the next coach is.
Clemson is an interesting situation to me. They return 4 out of 5 O-linemen next year, but the one O-lineman they lost was their only good one. I'd certainly guess the other 4 will improve, as it's only natural to get better with reps, but who knows how much they'll improve - maybe their ceilings aren't very high.
We know Clemson's new QB can throw the ball, and they'll definitely still be good on offense, but we also know that their run game was a lot worse without Lawrence (a dual threat) in the game. Take it from an Ohio State fan who lived through 2018 with Dwayne Haskins: a QB's threat as a runner definitely has an effect on your overall run game (unless you can field an O-line like Bama did in 2020 - something Clemson doesn't appear to be capable of).
The scary thing about Clemson, as much as I hate to admit this, is the future of their D-line. Bresee and Murphy were the best DT and DE recruits in the 2020 class and started as true freshmen this past season. They'll only get better, and I especially think Bresee will be a monster. Their other two starters in 2019 were good players too (Tyler Davis might've actually been their best overall D-lineman) and the two of them were both only sophomores. Their D-line could start to look the way it did from 2016-2018 again.
As for Ohio State, I think next few years will tell us a lot about Ryan Day. I like him and have a lot of confidence in him. He can recruit and he can coach, but some coaches struggle to maintain that success for more than a few years. He'll be breaking in a new QB next season, and we'll see if Coombs really is up to the task as DC. Over the next few off-seasons, we may also be facing a lot of turnover (Brian Hartline will be getting OC & NFL offers, Al Washington will be getting DC offers, Kevin Wilson will be getting both OC and HC offers, and Larry Johnson probably only coaches another 2-3 seasons before retiring). It'll be interesting to see how Day handles the potential turnover, and what he does to keep guys like Hartline and Washington (who both at least have OSU roots) on the staff.
I think UGA and Oklahoma will also be competitive, of course. Also think ND could potentially surprise us one year because I think Marcus Freeman was such a great hire for them as DC.
At the end of the day, if I had to make a prediction, I think Bama wins the most in the next 10 years with no clear #2.
