Aerospace makes my Mac usable, but it is a looooong way from what i3 offers in my experience. i3 is way snappier, super stable, with good features out-of-the-box (including a status bar) - you forget it exists. Aerospace is slow, has to use that "windows in the corner" hack, it constantly resets whenever I resume the mac from sleep, needs additional tool for a status bar and more.

Much of it is not a fault of Aerospace, it's just what you get using Apple products in a non-sactioned way.
