I went through exactly the same experience after trying i3. Also a Mac user. I couldn't move to Linux at the time because apps, so I did my best to recreate that experience on a Mac. Rectangle+Karabiner+Hammerspoon did the trick, and at this point I'm so used to it that when I set up my Linux desktop, I actually recreated the same shortcuts in i3 vs. the default i3 config.
So I would say if you _have to_ stay on a Mac, there are ways to customise and tinker too, with the end result much better than you expect.
