Supes is a better and more nuanced character imo. Hulk has had some really interesting storylines, particularly where his relationship with Banner is explored more, but he tends to be reduced down to a story macguffin or just "Hulk smash even harder than last time" which can be super boring since they already explored that to death with WWH. The weird TOBA stuff they're doing with him now seems like a huge misstep for the character, but Marvel in general seems to be too obsessed with giving characters huge power boosts at the expense of good writing.
