I used i3 on older laptops, and decided to try switching to Sway when I got my current laptop 16 months ago. I’ve switched back to i3 on it on a few occasions for screen sharing in Zoom, and wow, I’d forgotten how bad the tearing is, and how not-great the management of inputs and outputs (though this is unlikely to affect full desktop environments like GNOME and KDE), and how annoying it is to not be able to use my XF86AudioMicMute key because its key code is 256 (it was a pain to get working in Sway, requiring xkb_file with a manually-tweaked keymap, but as far as I can tell it’s simply not possible under Xorg which has a hard limit of 255). Plus scaling simply doesn’t work at all well in X/i3, to say nothing of flat-out not supporting mixed scaling, whereas it all just works in Sway (the only apps I have to tweak are ones run via Xwayland, which sometimes but don’t always get it right out of the box).
