> Sway makes switching workspaces and some window management functionality nearly instant in comparison. I've compared it with i3 and openbox; others have compared it with dwm. I'll see if I can find a link.

i3/dwm (or any X window manager), unlike Sway (or any Wayland compositor) has nothing to do with client window contents rendering. X and Wayland works fundamentally differently in that respect. Under Wayland the compositor and wm is the same. Under X the server and wm are separate programs in separate processes, and the latter is not involved in rendering the client window contents, only the window chrome, if any.
