I think it's fair to say that Colossus is one of the strongest heroes in the terrestrial Marvel-verse (everything changes when you get into the cosmic level stuff), probably at least in the top 10.

The top two in that category are probably Hulk and Namor, depending on the conditions they are in at the time. The next two are probably Thor and Hercules, but they're gods so that's not really fair. The Juggernaut is definitely one of the strongest on Earth, but he's also not really a hero (usually), and if you're including villains that opens up a whole different can of worms. She-Hulk is technically towards the top. Ms. Marvel (and Rogue when she had Ms. Marvel's powers), Sentry, and Wonderman are all very strong. Strong Guy and Sebastian Shaw are both capable of extreme feats of strength, but only under certain conditions and at personal risk. I would personally put Colossus, the Thing, and Rockslide right below those characters, in that order.

Given all of that, and the conditional nature of many of their powers, I think it is fair to say that Colossus is one of the top 10 consistantly strong heroes in the terrestrial Marvel-verse.
