Debian on my personal computers and servers.

Ubuntu on my work desktop, RHEL on work's servers

I wouldn't consider Debian "Canonical"-y, it's just what they happened to pick as their upstream.

I tried some of the atomic distros, but ran into too many problems. When I buy a new computer, I sometimes have to run Opensuse Tumbleweed or Arch to get new enough hardware support... Too lazy to rebuild my kernel and mesa at home
