I put the Debian 10 RC on my main workstation, and — knock on wood — it's been rock solid so far. I'm incredibly happy with it. The only major modification I've done has been replacing Gnome with i3wm.
Believe it or not, after 26 years of constant Linux use, this is my first time running Debian. It's a great first impression. If you're on the Debian team, please let me buy you a beer, won't you?
