There are a few things about Linux that I miss, most notably decent tiling window managers with multiple display support. XMonad was a dream to use, allowing me to throw windows or entire workspaces around the place with a couple of key presses.
I don't miss them enough to move off macOS though. I'm deep in the Apple ecosystem largely because the integration is miles better than any of the alternatives, I can bounce audio around the house with Airplay, I can start watching some TV on an iPad in the kitchen, then when I've finished cooking throw it over to the TV. If my phone rings I can pick it up on whatever device is closest to me. Apple's integration between devices is about as close to the sci-fi future we were promised as you can get at the moment, and there's no way I want to go and try to replicate a half-arsed alternative on Linux.
