The snap thing was annoying, but not a major problem for me, except for one thing: I switched Firefox back to a debian package, following the directions online to do so, and every few months it seemed somehow I had been switched back to a snap version. I removed the snap and all of that, but every now and then I’d realize I was using Firefox in a snap. (It became obvious when I tried to unlock 1Password - the snap version relies on the plugin, but the non-snap version fires up the standalone 1Password program.)
In general, I’m not opposed to the concept of snaps, and a browser is probably something that should be in a sandbox. But, I preferred the standard Debian package installation, and somehow that kept getting overridden. And that is the kind of thing that I hate about Windows.
The install was smooth, or would have been if I hadn’t had a slightly unusual setup with my drives. It works just like Kubuntu, by switching to KDE with X11 (I had a few minor issues with Wayland), but without Canonical. I don’t need bleeding edge, I just want my system to work reliably.
My Linux background: Spent a lot of time with Slackware starting in the late 90s, both on server and desktop. Switched desktop and laptop to Kubuntu around 2010. Server got switched to Debian in 2017 or so.
