#1 Adam Cole
Adam Cole is one of those superstars who has that much-wanted "it" factor. Whichever promotion he's gone to, he's been a top star. Even when he debuted in NXT in 2017, it was evident that Triple H was eventually going to make him NXT Champion.
The best part about his run in NXT is how he was gradually pushed over the course of 22 months or so, slowly building him up for an NXT title win. And when he did, it was a clean win.

The fact that he's a leader of a faction only helps him out, but we don't know how the rest of the Undisputed Era will fare, especially looking at how Sanity did in NXT and how they did in the main roster.
However, one thing is almost undisputed - Adam Cole will be a top star in WWE and he won't get ruined by the main roster.
