Top 20-somethings

Following up on the The WWE Roster is so old thread with a simple question, albeit one that is perhaps better addressed to your readers:

Who are the top wrestlers, still in their 20's, that aren't already on the Raw or Smackdown rosters?

They’ve got TONS of guys in development that will probably never make TV even.  Enough that they’re doing the rumoured secondary version of NXT to give them some time.  But Tyler Bate and Pete Dunne are clearly two of the best in the world right now.  Also Rhea Ripley and Toni Storm on the women’s side.
