Thanks for your points of view! I agree that Stable comes at a cost, and of course if I ever were to set up a server Debian would probably be my choice.
Regarding derivatives, I know about Ubuntu, Mint, etc., but I don't exactly like distributions tied to or ultimately dependant on commercial entities (I want a change of air after going through Ubuntu, openSUSE...) I have also seen independent Debian derivatives (MX Linux comes to mind), but they either used backports or the Testing distribution. I would happily consider using Debian Testing for example, but wherever I see someone asking about it I always find someone discouraging from using it due to the possibility of having broken or unsecure packages for a long time due to it being automated. Is it actually usable for a Workstation? The same would apply to Sid, I can no longer allow myself to fix big breakages after broken updates (I don't know if that really happens often in Sid) Thanks, Sam
