The window (miss)management of MacOS is what's holding me from switching to Mac. I've already tried Aerospace and similar solutions, but I can't replicate the fast and unobstructed experience I have with i3wm.

Sadly wm in MacOS is like notifications on iOS: with enough time you get used to the unproductive mess they are, but you'll be missing out on better solutions. And since probably all MacOS devs are using Mac, they won't see/understand other (better) approaches.
