If X works, why bother? If you're missing something it's not hard to test, but if there's nothing driving you to it then why bother at this point? It'll keep getting better over time

I honestly only notice the difference once in a while, when an obscure app isn't compatible. And screen sharing is still kinda hit or miss.

On a whole, the momentum has shifted: developers have shifted to Wayland.

I've switched to Wayland. On GNOME I haven't noticed any benefits, nor any costs. It has been a no-op.
