I work on multiple tasks too, it's just all of it is done is either in a browser tab or terminal tab. Usually those live in separate virtual screens, but one of my machines has an ultrawide, so I can comfortably put 2-3 tiles on it depending on what I'm working on.

Tiling is all about efficient use of space (and wasting all gains by adding cool looking gaps to post on UnixPorn). I find floating windows just hard to navigate and wasteful when 99% of time I want the app to be in a full-screen. Hence why macOS splits get me pretty much where I want to be.
