I think I am 4, it's too hard for me to manage my own distro and update my packages when this will be EOL, so I have to wait and see, is there any alternative to CentOS aside of Debian and Ubuntu ?
Why not Debian? I've always used either Debian or Gentoo, depending on what I'm doing. I know Gentoo isn't everyones cup of tea, but Debian seems similar enough to Centos in my eyes.
EDIT: Reading elsewhere in the thread, the answer seems to be “enterprise”, which I consider something to be actively avoided.
