If all you're measuring is the sheer capacity of one's suffering, I may be inclined to give it to Mebius, but if sheer capacity is all you're measuring, you might as well just make it a tier list, since characters that can experience more planes or aspects of reality at a time automatically become superior to those who don't, 90% of the time.
Part of what makes a character "in need of a hug", to begin with, is emotional vulnerability. That is, to say, mindset. It's not enough that bad things happen to them, or that a lot of bad things happen to them, because there is no necessary causal link between those things happening and their eliciting the normal negative emotional responses we, as human beings possessed of the context of a human experience, tend to associate with those experiences.
...comparing Mebius, in this instance, to Gal just as an example- and, more broadly really, most any other contestant I can think of probably- Mebius is a countless-millennia old godling, with the intellect of a supercomputer and the ability to outright break higher-dimensional psyches, travel to any place or time, and so forth entirely on a whim. Suffering barely even matters to an entity way below the point that Mebius has reached because there's nothing stopping him from experiencing just as many simultaneous happy possibilities, or literally rewriting the Plot of the story itself to suit whatever his whim happens to be. There are, in the profile's own words, zero meaningful limitations to how he can use his immense array of busted powers to make any setback he faces completely trivial.
Now, compare Gal. Gal is comparatively a child, still in his 20s, one whose entire identity and aspiration is founded upon his desires to do heroic adventurer things, and who is confronted by the rules of the world around him, mere happenstance- cruel fate- actively going out of its way to violently and traumatically deny him that one thing with acute visions of what the end result of his actions will be. And, in this case, this is happening to ostensibly a normal perso, more or less- hence, he fails. Which, really, is the crux of what makes a character in need of a hug- their setbacks and the darkness plaguing them actually weighs on them in some meaningful sense. Gal can't simply change the rules of the world he's in at a whim, or otherwise trivialize what bad things he goes through- and that, I believe, is what people want to see, when they want to see a character that "needs a hug."
Remember, a mere man lifting a boulder is far more impressive in the ways that it actually matters than Atlas holding a mountain like a tiny pebble in his palm.
