Look in "the incredible hulk" no. 456 and 457 for hulk versus juggernaut. 456 shows hulk getting choked by apocalype it also shows hulk getting fully unleashed and somehow had some sort of energy boost thus becoming the horseman "war". 457 shows hulk getting pushed by juggernaught and also juggernaught getting stopped by hulk. All these jugs vs hulk was just apocalypse testing for the coming of the celestials.
I would go with jugs in normal battles, even with enhanced abilities hulk had trouble with jugs. However neither hulk not jugs are unstoppable or immovable.
The only thing that TRUELY stopped both the juggernaught and the hulk have been onslaught (hulks ripping of onslaughts armour was not a show of strenght on hulks part, it however released onslught from a physical body thus making him more powerful).
