Hercules
Count Of Durfisto
Wasn't Warrior created to test Gladiator?
Didn't Thanos despite the fact he was four times stronger than him, consider him the weakest of the Thanosi because of his limited interlect?
The way I see it, if Warrior has all Gladiators strengths and none of his weaknesses, then due to his limited interlect and eagerness to fight, these two slug it out.
I can't see Gladiator overcoming Juggernaut's enchanment with strength, ergo I can't see Warrior doing it either.
On the flip side, I'm not sure if Cain could put down a Gladiator at full confidence, so I'm unsure if he could put Warrior down.
I see this could just be one huge stalemate without BFR.
However seeing as Mystic was a notch below Strange, Warrior could be a notch below Gladiator.
Being four times stronger than Thanos physically doesn't mean he was four times a POWERFUL, he definetly had no where near Thano's brains, thats for sure.
I don't believe we saw enough of Warrior to judge, so I would go with a stalemate without BFR being involved.
