The main thing is that DC's and Marvel's heavy hitters are different. There isn't really stuff like Class 100 in DC just very very strong ones who become stronger and stronger till they are overpowered. The other nice thing is when Colossus is stopping an Express Train in Ultimate X-Men #10. We all know that a train (normal train) is over 100 tons and it also had some speed. The other notable things are the classic stuff era (i call classic stuff 60s-80s comics stuff). Wonder Man is notable when The Thing is struggling with lifting the training weight and Wonder Man easily lifts it up and bends it. Classic Juggernaut is well known as good as The Hulk. The "heavy hitter" Sentry is the one I'm very curious about. Also "Class 100" strenght without agression isn't all there. An all out character like Black Adam should be able to do more unlike Supes who is holding back most of the time.
