If you use a Linux desktop professionally, it's only a matter of time until you hit that one GUI app that you need, that is only supported on Ubuntu.
I prefer Tumbleweed, but the sane choice remains Ubuntu.

So much for that Linux ecosystem compatibility, Linux apps not even compatible with other linuxes!
Distrobox exists for that very reason. No need to ruin your main OS just to run one app.
Both Arch and Nix solve this by making it very easy to write packages that work around the compatibility issues. When I used to use ubuntu and mint it was a lot more common to run into these types of issues.
