I'm talking from experience both in education and sysadmin duties. In my life I helped hundreds of people switch to Linux, for work, for home, for everything in between, and was that helpful person that answers all their questions. I have the statistics, however informal, I know what I'm talking about. There are whole categories of problems that people encounter with Ubuntu and it's derivatives that just categorically don't exist in Arch. And you can trust whatever the fuck you want.
