100% agree. Snaps are kind of neat for server stuff (easiest setup of Nextcloud I've ever done, even though I switched to Docker in the end), but man the desktop experience is god awful.
I had to setup an Ubuntu VM at work to run something I couldn't do on the Windows host, I tried to open Firefox and it took ages to start. I literally began trying to troubleshoot why it wasn't opening before it finally started. Completely unusable and I have no idea why Canonical thinks this is an actual competitor to Flatpak.
