Probably this was asked before many times but I want your updated opinion.
1) What is the best Linux distro you used? Why?
2) Do you still use it? If not, why?

My answer:
1) Debian. Because I find it very comfortable and it run in Raspberry Pi and other small computers. It has the software that I usually use and it's very light.
2) Yes but not as my main OS because the lastest version of software that I use weren't updated yet (and probably they won't update them on a short time). I had to move to W10 as my main OS.
