I stopped using debian for a while after a botched upgrade (bo->hamm, some sort of libc4->glibc issue) and switched away. But that was almost 24 years ago, so I guess this system predated that.
One mistake can really turn someone away for good, but also wondering if you have had another poor experience with whatever you (initially) replaced Debian with?
Before debian I used TAMU distribution. After Debian I switched to Red Hat 5.something and stuck with it through the extremely weird Red Hat 9 era, which had its ups and downs. Next I switched to ubuntu and have mostly stuck with it, mainly because the packages are fairly well done and it gets an LTS every few years. I have dabbled with debian (missing some features in ubuntu), and several other OSes, but these days, i stick with what represents the least-effort path for dev compatibility (ubuntu). I admire arch but it's not the standard.
