i run Pop now, been running it for the last year or so. before that, i was on elementary OS for several years. i honestly prefer Pop. it's been very solid.

I meant with cosmic.
I now use my own version artix & devuan. Both styled on #! (Crunchbang)
My wife uses mxlinux.
If I was going yo use an Ubuntu derivative, I'd go with Mint.
However my main choice is because of systemd - just too heavy and too many bugs lol!
