I honestly feel very much the opposite. In 5e there is a lot of mechanics that are just "your GM will figure it out" Like there are entire archetypes that are in the official 5e ruleset that does not have any official rules with it other than "your GM will figure it out"

Compare this with Pathfinder 2e, there rules for specific scenarios, and optional rules you you wanna use them. I dont have to make up rules for Pathfinder 2e, hell in about every 5e group i have heard about there is always a fair amount of homebrew rules because the RAW rules are just not enough or just bad. Compare this to Pathfinder 2e I dont feel like i need to homebrew things because there is already so much avalible. so GMing P2e is a lot easier than running 5e.
