I definitely prefer it over Snaps or appimages. Straight-forward to update, and Flatseal provides a nice GUI to control permissions (if needed). Themes may not work properly, but whatever, not a big deal for me.

The distro’s repo is always my go-to. If it’s not available there, then flatpak, and I’ll use appimage under duress. If that doesn’t work, I’ll figure out a different solution.
