i would like to give you a demonstration to let you know that hulk is stronger than both superman and doomsday. when superman and doomsday was going all out in metropolis, they were shattering windows. when hulk and onslaught was fighting, every swing of a punch that they were making, created a tornadoe's, no one could get close enough to witness the fight, trees was uprooting and everyone was flying back.
With that fight with warpath, juggernaut was laughing at his effort but unlike doomsday who was getting pummeled by maxima and knocked thru gas tanks by weaklings, that you dont even see in comics, thats pretty impressive huh.
You say that doomsday to a 1000 nukes but he got disintigrated by imperex, wow, what great durability. you say that doomsday have great durability but when he fought superman again superman was slicing thru him with a sword, (which he healed it afterwords). Juggernaut durability is on another level and his strength is unlimited. If juggernaut wanted to, he can put up his force field and walk thru anything that doomsday throws at him but he chooses not to do that because he is totally indestructible already, he dont have to.
Like i said before jinzin learn more on juggernaut before responding on how a battle would go between him and juggernaut.
