You could easily spend 500 points on both, have Hawkeye's arrows being less powerful than Mjolnir, by the order(s?) of magnitude the fiction says (given that the fiction is hard to pin down, there's some latitude there), but still have both be participating in the same battle meaningfully.This is more about the genre than game systems. I mean, sure, in Champions one can easily spend 500 points on both Thor and Hawkeye and have Hawkeye's arrows doing the same damage as Mjolnir. But it wouldn't be true to the source material.
It's a cute trick or dirty little secret, depending on how you look at it, fans call "Hero doubling" - while each "damage class" makes a power only a bit more effective at taking down an enemy, it represents a notional doubling in raw power (this is, again, however un-intuitive, weirdly realistic. which is ironic for a superhero game

But, yeah, if you're hard over on the fuzzy power of "unlimited strength" the MCU uses to dodge "whose stronger?" questions, nothing concreat can really model it.
(lest some other Hero fan say it, yes, you can go quite a ways with heavily limited extra strength and EGO-rolls to push and uncontrolled powers and whatnot... but, ultimately, points are quantitative and finite)
