lol, you realise there is no absolute 'stop' so slowing down something to such an extent that it is redirected and/or that momentum builds up that it cannot then control, is basically proving that your strength overmatches its.
like a charging 5yr old who you hold at bay by placing your extended hand upon his head... he builds up momentum, because he doesn't have the strength to overcome your power but, once you let go, he can't control the momentum he's built up and he crashes into you.
just read some of Hulks past achievements, and honestly, the character is designed to wreck reputations and characters such as juggernaut.
he defeated the High Evolutionary's armour, with the HE inside it, ripped it to pieces in an hour - according to the HE.
another Elder of the universe, The Gardener had the Soul Gem taken from him by Hulk. he was astounded that the Hulk had power sufficient to match/overmatch him.
Apocalypse says his Celestial Tech reports that the power that The Hulk +generates+ (not some ultimate potential, but the power Hulk could realistically output) might be enough to challenge The Celestials.
the problem with the Hulk - Juggernaut conflict in the recent WWH arc is that Hulk just doesn't have the slightest bit of interest in juggernaut. he's not bothered, juggernaut is an insignificant factor, as is everybody else who is not part of the Illuminati.
also, and quite clearly, The Hulk fought all the X-men while severely holding back, with the safety-on, no kills no permanent damage, just enough to get the job done. so, naturally, the easiest way to beat juggernaut is not for Hulk to gee himself up to break Cyttorak's pet, but to simply bfr him using his superior strength and intellect.
