Debian 10 “Buster” Released
I used to run Debian, but I switched to Fedora a few years ago and haven't looked back. Fedora is always sleek and up-to-date, unlike Debian, which due to its outdated packages always ends up looking like the plain step-sister. I also strongly prefer DNF to apt. With that being said, they both play crucial roles in the Linux ecosystem - Debian being the base for Ubuntu and Mint, and Fedora being the distribution which upstreams the most code.
