I am trying to stick with "original" distros and not spins (Debian, Fedora/CentOS, Arch, openSUSE, Solus etc.). That decreases the selection a lot but makes it easier to choose a distro without the need of endless distro hopping 😄
Currently, I am looking into openSUSE Tumbleweed. The syntax of zypper is intuitive just as in Solus. I am still not certain, if I really want to go with rolling release or static release model (e.g. openSUSE Leap). Arch is nice too by the cryptic syntax really bothered me.
So, instead of Solus I would go with openSUSE 😄
