superhumans are more
super strength, durability, energy projection, speed...
mutants are more
reality warping, weather manipulation(Thor and he's better a it), time travel(Who?), molecular control(Molecular Man,Silver Surfer)... shutting thousands of minds down with a single thought type abiltys...
That's a very biased comparison, there are heroes on both sides that can do all of these and more,and as you said few mutants have those,most of them have more "normal" powers.
of course he is & Im referring to superhumans not Gods or cosmics so Thor & Silver surfer aren't in this
Time travel, Cable, Nate grey, Legion, Rachel grey, Trevor Fitzroy & a many others go into time manipulation like Sway, Eva, Velocidad ect
Most superhumans have powers like that though enhanced human abiltys & yes there are plenty of mutants that have normal but majority of them do have powerful/weird/different ability's they call em Homo superior for a reason you know
