My friend ,who got imto Linux in the first place, is taking a Networking program at a local University
UCFV (Univ/College of the Fraser Valley)
part of his program, actually a big part, is Apache
running on redhat
He's even got a Linux Admin course in the program.
He said that they were using 8 but dropped back down to 7.3 because it was a more comfortable networking environment.
