sway doesn't have rounded corners, animated transitions, etc. i like it that way because if feels snappy and has just what i need and like

there's also swayfx, a fork of sway that has more effects if you want sway but also want more stylishness

hyprland is very fancy and can look really good, i have used it before and you can configure animations with (bezier?) curves, have rounded corners, have gradient borders, and more. it's a matter of how much eyecandy you'd like.

also, sway is like i3, so it's manual tiling, i don't remember how hyprland tiling works but i recall it being pretty good
