I would say, using upper-feats as a far-goalpost, and general feats as the expected median, it would *likely* go as follows:
Superman (physical strength)
Magneto (magnetism, assuming applicable to the situation at hand)
X-man (while I give Mag's the 2nd rank, obviously X has more versatility in terms of applicable force, which of course circumstantially can give him the second spot, depending on specifics...)
... or something like that...
