It works the same. What I like in sway is it's basically i3 AND i3-gaps together in an active codebase. The biggest difference you notice is when you get rid of picom the compositor, you'll get visibly snappier desktop... Without really needing any special xorg configuration or picom setup, you get composition, tear-free graphics and videos, all just working.

Be aware that to get there, you should make sure you run all your apps in wayland too, not in xwayland. Firefox requires an env var, same goes with GTK and QT apps. Emacs you get from the NixOS overlay; there's a branch that follows the pure gtk build, that doesn't need xwayland. Electron is still xwayland only for most apps. I'm eagerly waiting at least for slack and element to upgrade to Electron 12, which will bring native wayland support.

And there's a nice ecosystem building around wlroots and sway, great tools to choose from for your desktop needs, such as waybar, wofi, wf-recorder and greetd.

Of course you don't NEED any of this. But if I would think like this, I'd probably just used a macOS machine with default settings anyhoo.
