If I was willing to deal with Oracle, I would use it. My experience was that on the correct sparc hw, Solaris was always more reliable under heavy IO load than Linux, in that it would degrade gradually in performance as the limits of the hw were reached. I also much preferred Solaris RBAC to sudo; and SMF to systemd. And, the old Sun support that you got at the platinum level was tremendous, and as they owned the whole system (userland to hw), they could have all the ppl. that designed the parts you were having trouble with in the same room, or on the same call, to help you fix it. Of course, this was not cheap.... TL;DR: I miss SUNW.
