Too many factors. Team ups or unlucky shots while unaware make this too chaotic.
It's like this
will Rulk absorb Jugg shields?? He tries but gets smacked by Bill or Lobo. Gladiator fights a bad matchup like Lobo and loses confidence for the late game. etc etc. No way to tell.
Classic Juggernaut comes out on top. He just waits the 1000 years until everyone wears themself out. The only one who comes close is HP Doomsday who may beat Juggs if he wasn't occupied with everyone else.
I'd say ghost riders assuming his Stare works on everyone
