You can use many champs for initial clear. For exploration you can also get it done in small resources and time with a few champs. Aegon isn't the only one who can do LoL 100% nowadays. The best? Sure. But a mixture of champs can do it to varying degrees almost as good as he would.
Guillotine 2099, starlord, sparky, ghost, stealthy, shehulk, void, synergised blade, domino, Colossus, nick fury, are some of the best labyrinth options nowadays. Void for the really niche fights like x23 and doctor strange, while the others can slay the paths!

In general, it's only worth if you have AEgon and you can do it in few or none units spend.
It's fun though.
