Stable just means no major version jumps in software that might break your current setup. That's important for operating servers, not desktops.
I use debian Sid (unstable) at work and never had problems. Most of the time I get updates prior to other distributions I am using.
At home I use arch (derivates, manjaro), with great success.
I would abstain from Ubuntu. There, I had problems, it is very opinionated and not in s good way.
In a general sense I would always chose a distribution that isn't too locked in to a certain desktop environment and provides updates, quickly.
