@DarcMoughty @syllopsium @peterrenshaw @aj This matches my experience pretty closely since around 2018. I really appreciate the strides the Wayland devs have made. I'm amazed by how well Xwayland works. Meanwhile, GNOME feels mature and stable, and stays out of my way. I run a half-dozen gnome-extensions which I hope don't die on the vine, including a couple just for fun (eg "Burn My Windows"), but otherwise don't feel the need to customize it.
I'm also impressed with System76's Cosmic. I haven't tried any other DE in the last ten years that's more likely to supplant GNOME on my desk, but it's not quite mature enough for me yet (especially rough edges in handling Citrix workspace windows).
