Snaps could work great on servers, at work we have a CentOS server (via hosting is not our own), I am a developer not a sysadmin and I don't want to mess with the package manager and break something on this server(it is running a bunch of stuff)...anyway today I had to download and run a linux binary , it was a .tar.xz and it worked, would have been even better if I could be sure this binary was sandboxed.

On the desktop I use Kubuntu LTS, snaps will allow me to test or run software that is not in the repo or it is an older but sable version in the repo, IMO snaps provides extra options so if you do not need it you should not use it.
