Hero
Given how often both Jimmy and Lois have had superpowers over the years I'm not sure they're ideal examples, but I get the gist of the argument.The other arm of the "Jimmy Olsen problem" is to note that raw superpower is not the only way to influence the narrative. Lois Lane doesn't have superpowers, but she moves stories forward by sticking her nose where it doesn't belong, learning what's going on, influencing people with words, and being emotionally important to others. A game that allows high effectiveness at these things, or other "mundane" ways to move a story, without use of outright superpowers, allows for effective disparity in character "power".

One other possibility might be a supers game where everyone makes a hero PC and also a competent but non-powered PC that's some other player's supporting character, playing one or the other as the situation dictates. Sort of borrowing from Ars Magica's troupe-style play, and you could even add in the opportunity to temporarily play as innocent bystander "grogs" when appropriate. Might be best with either a very small table (2-3 players?) to limit confusion, or maybe a campaign where the heroes and supports are all part of a formal organization, like an government-funded hero team with specialists attached as liaisons.
