Hulk is still the strongest, . Spidey was for one issue I guess, , but that was it. As for Hulk not being able to lift Thor's hammer, that is nothing to do with strength, but mystical forces. Juggernaught beat Thor up quite badly in the early 400's, can't forget that one. We are forgetting Silver Surfer who is in the same league as these heavy hitters, Thanos, who has the brains with the brawn, Abomination, bit dumb, but very strong. Superman, who is as weak to magics, and mystical things as he is kryptonite. Hulk still wins, and a close runner up Thanos.
