Current Juggernaut vs Current Hulk - Juggernaut. Hulk's not exactly at the top of his game right now, but Juggs is.
Classic Juggernaut vs Classic Hulk, could go either way. These characters were unbelievably strong in years past. They fought many times, in fact. Slight edge to Juggernaut because he was really extremely strong back then.
Early 2000s Juggernaut vs World War Hulk was a curbstomp. Hulk was at his absolute peak of rage, but kept his intelligence. Juggernaut was only able to lift around 70-80 tons. This led to Juggernaut regaining his full power, though.
X-Men 3 Juggernaut vs Edward Norton Hulk - Ed Norton takes this. Juggernaut went down way too easy in the movie, and his most impressive strength act was running through a bunch of walls. However, Ed Norton Hulk had the Green Giant taking RPG hits and supersonic waves.
Marvel Vs Capcom 2 Juggernaut vs Marvel Vs Capcom 2 Hulk - Juggernaut by far. Hulk is low tier, Juggs is upper tier.
Is this a satisfying answer?
