I'm currently using XFCE on two computers with key bindings for snap left/right and snap top-left/top-right/bottom-left/bottom-right. On a big display, this setup is excellent. On a laptop it works, but often feels a little cramped, and it's particularly painful with a laptop trackpad instead of a mouse. It would be nice if there was an option to split ~67%/33%... apparently Windows(!) can do that.
I've also been playing with i3 on another laptop, and for a lot of things the experience is clearly better (e.g. web browsing on a laptop without a mouse), but for others (e.g. kicad) it either doesn't work well, or I haven't managed to configure it well enough yet. The rabbit hole is infinitely deep, and while I enjoy tinkering with it every now and then, I'm probably not going to use it as a daily driver anytime soon.
