I used i3 for the longest time and I'd say a wayland based alternative like sway or miracle is a better choice nowadays. Even KDE Plasma recently dropped x11 support [1] so going forward, most apps will target wayland first.
Migrating my i3 config to sway hardly took any effort. I was also able to get rid of a lot of xorg specific configurations from various x11 dotfiles and put them directly in the sway config (Such as Natural Scrolling)
