Never said that it should be physical strenght. We are talking about the literal definition of strenght, I've already posted a link before, check it if you want. Zed, SOK wasn't able to kill that one vampire (Forgot his name) since his guns couldn't kill the undead. Doesn't that make Alucard his natural counter, despite him being..immortal and stuff? I mean.. Like SOK could 1 shot Hulk no sweat, Hulk isn't even a contest against SOK in my eyes.. But with that aside, Alucard can simply disappear and reappear at will, while existing and not existing in the same time. Can you kill something that doesn't exist?
The Hulk's strength falls under the literal definition of strength. While this entire subject is pretty much based on opinion, I don't think you can convincingly present "Hulk isn't even a contest against SOK in my eyes" as an argument. Saying things like SOK killed a God doesn't really do much to support the argument that SOK is more powerful than the Hulk, given The Hulk has overcome gods before. I don't see anything wrong with favoring the Hulk simply because it's always been a case of "Hulk gets angrier until he wins or some shit" with his writers. If we're talking about the literal definition of strength, Hulk's capacity for endless power feels like it should trump anything else.
But I mean, the hulk has been defeated
When he came back as world war hulk, he fought sentry in the end and just barely lost, but still, he lost
When was this? I don't remember Hulk losing anything. In World War Hulk, Hulk spared The Sentry from death.
