@bograt i just don't want anyone to make decisions based on me, a random internet stranger :)
it depends on what you want. i think those things prepare you to do standard sysadmin stuff with a standard distribution (which, tbh, pays the bread). those are _really_ different from how things would be done "the unix way".
@bograt i never used solaris.. i think redhat etc. have really "baroque" solutions for things, as it is common with enterprise stuff. professional != complicated. take sqlite for example, it's rock solid but isn't overly complicated.
@bograt that said, what little i know of solaris was of course "enterprise" but rather well thought out. modern linux is a hodgepodge of things, even more than it was, say 15 years ago. things get replaced _all the time_really by overly complex stuff regardless of if it is really necessary.
