There are fewer "Dual Champions," across two divisions, then there are "Olympic Gold Medalists" ...
If Henry was a dual-Gold Medalist, I would agree.
But a gold medal in wrestling is a dime a dozen, compared to a two-weight class World Champion Boxer or Kickboxer.
It is very rare to be able to do this ... especially dual across two platforms, like Alex did.
Alex also has KO'd people, in both divisions, who had never been previously KO'd before.
Cejudo's win over DJ is questionable — and his win over Moraes hasn't aged well. More ice was never Champion.
Alex has beaten/KO'd two CHAMPIONS in MW (Adesanya/Strickland) who had never been KO'd before the UFC.
Alex is beaten/KO'd to CHAMPIONS in LHW (Procházka/Hill) who had never been KO'd before in the UFC.
Henry has done no such thing, not even close to that level of dominance.
