In Kubuntu I disabled snap entirely. Never needed it, and simply replaced Firefox with a mozilla PPA (and a blocker to prevent the snap version from being installed accidentally). Avoids multiple reported issues with the snap version of the browser. As for the store I never used it, always figured it was not as useful as synaptic. I'm guessing KDE's Discover is the base Ubuntu equivalent.
Guess my point is the distro (and especially desktop environment) you spend time experimenting with can radically change your perception of Linux a LOT. If Gnome was all I was exposed to, I'd never have switched. But others think otherwise so I'm not going to say they're wrong. That said, when you spend your life in Windows you can easily ignore the rough edges in that OS as well, often without even realising you're doing it. So long as people don't insult one another for their OS choices however.
