From what I've gathered I'd say the stats shake out more like this, Juggernaut 6' 10", Hulk between 6' 6" and 8' depending on his "form". Yes, I've seen the Marvel.com stats that show Juggernaut at over 9 feet, but most sources I've found, outside of that one, show him between the upper end of 6' and 8'. Again looking at this breakdown the two are very close in height, and so that's why I'd prefer to have them be closer in height in figure form. Hence, my opinion of this Juggernaut being too big.
And yes, I'm aware this is based on the game's version, as I'm sure most are. But possibly more to the point, when you're deciding if this better sculpted, better articulated version will work as a comic version, the answer is unfortunately no. Which is why I felt he was too big. The game version always seemed comically large even in the context of the game itself.
