I don’t like Snaps either, but it isn’t a that big of a deal. Ubuntu is still vastly more private than Windows. I do prefer Fedora much more because it actually sandboxes system services with SELinux polices. Snap creates a better sandbox for applications than Flatpak, but it is slower to launch applications, depends on AppArmor (which is less secure than SELinux), and uses hard coded package repo (centralized design).
Cinnamon with Wayland is still in testing. X11/X.Org is unmaintained software and is less secure than Wayland. GNOME is the only desktop at the moment that actually protects the screen from arbitrary recording by applications. Just food for thought.
