Depends what you run, I suppose.

I have natively-packaged browsers: Waterfox and Chrome.

In Snaps I run less essential but workaday stuff: Ferdium (my multi-protocol messaging client), Slack, Signal, Telegram, Skype (RIP), Spotify. I don't care if they can't access my filesystem; I don't want them to.

All are trouble-free for me.

I used to carefully remove all snaps, then do `apt purge snapd`, then block it from being reinstalled. After that I installed deb-get:

And then I used that to get, install, and update all the apps I needed that weren't in the Ubuntu repos.

It worked very well, but Ubuntu version upgrades were hazardous: the best result will be that the `do-release-upgrade` tool disables them all, the upgrade works fine, then you have to go through and manually re-enable them all, where necessary, editing the apt `.list` files to point to the new version of each app's repo.

It was a PITA, and that's why now, I recommend just leaving snap there.
