I wasn't really having any problems per se, window management on macos is a bit lacking and I'm not fond of the forced animations everywhere, but overall I was pretty happy with how everything functions.
Until few weeks ago I had free time and an adventurous mood to try out the Asahi (It's really painless to do so), and the moment I git clone'd my dotfiles and logged into my old i3 configuration I was very astounded by the sheer snappiness of everything, fingers remember all the shortcuts and all of the workspace switching is /instant/. That's something I have tried to replicate on MacOS multiple times and always failed, yabai and the like are not even close.
I still reboot into macos for when I'm mobile as I don't trust sleep on asahi (I don't think it even works that is), but when I use it at home I am very impressed by how stable and daily drive-able it is if current (admittedly, significant) compromises work for you.
