[spoiler]It wasn’t JUST from wearing the gauntlet, everyone was shown to have visible damage from performing the snap. You can see everyone was damaged from the power of the snap, which is what Hulk did after putting the gauntlet on. There’s nothing from Hulk putting on the gauntlet that we can see and nothing that was said that involved the stones “going crazy” on him.
All he said was “You know, I tried. When I had the gauntlet, the stones, I really tried to bring her back.”
Thanos is reliably shown to be much stronger than Hulk. He won literally every fight until he got dusted. Do you really think Hulk could have done that? Thanos is insanely strong and resilient - this we can observe. We can also observe his skin is very thick because in Infinity War, Iron Man barely managed to scratch him with all his attacks - “All that, for a drop of blood.”
You’re absolutely right that there should have been a power surge on Tony - I personally think that’s a movie flaw, but the only reason it was inconsistent with Thanos and Hulk powering up was because it obviously looked much cooler that he said his iconic line and snapped. Oh, well he died anyways from doing it. Like what had been warned by Hulk before he put it on. And the damage matched what happened to Hulk and Thanos eventually.[/spoiler]
