Merged Hulk is hit by BN blade and it seems like it cause BN pain instead of Hulk since he is making the pain noise.

Juggernaut was hit by the same attack and makes the pain noise. The same attack that Hulk tanked.

Juggernaut on the ground holding his stomach.
We saw what would happen if the two met during the Hulk's visit of the X Men. The Hulk displayed more strength during his visit than he did as War IMO. I'm convinced of it because Cain was unable to plow him through any stretch, but only budge him a few inches. Cain would be in for it, and I mean, the Hulk would turn him into a rubber wrecking ball.
Inevitably this is just a stalemate.
