Doing stuff from terminal is easy. Finding anything on their forum is easy. And they answer all the questions. I got all things UNIFI, same as the guy that made the post, and I am not network engineer. Setting up the networking was easy and fun.
It's certainly not rocket science, but I don't know too many junior sysadmins who could do it without hours of research and pain. Whereas making a change on an EdgeRouter is more legacy - find, apply, save. Done.
