My primary dislike is that gnome continually focuses on touch-centric UI over desktop UI and occasionally makes changes just for the hell of it which bother me and break extensions and themes. The recent changes to buttons just feel like they're chasing Android.

Despite all of that, when combined with a few extensions and customizations it remains my favorite despite experience, despite the vanilla experience being sub par. But not when it's broken obviously.

It's a love hate relationship.
