I think those categories are so broad that they disguise how many systems exist.

I don't think I'd for example call DND extremely crunchy when systems like GURPS exist. And GURPS also has derived systems like Traveller.

Then you've got the various Gamma World editions that vary from "basically just reskinned DND" to "I took a bunch of ketamine while watching math tutorials".

You've got insane systems like FATAL, where even wholly putting aside the gross content, the actual system is actually insane in how it insists on statting basically everything. EVERYTHING. So it takes like ten hours to create a character.

More playable you've got games like Inquisitor which are almost more skirmish wargamey in rules and require the players to push the RPG elements themselves. Yet at the same time the homebrew Inquisitor community has popularized "Inquisimunda" rules to make the game even more wargame like. Is that more or less crunchy? Kinda both I guess.

You've got sibling systems like Call Of Cthulhu and Pulp Cthulhu which people sometimes interchange depending on the session or they mix-n-match to make some kind of hybrid homebrew creation.
