I recently converted the SO's parents to Linux, and I am quite surprised how smooth the process was after I finished setting everything up for them.
It was a bit contradictory for me, in that I do feel Archlinux wasn't the best choice for them, however they insisted on they wanted a Linux for which support won't be dropped and keeps getting updates and newer software ect., and will work well enough for years to come. So I thought rolling release. If CentOS 7 was out by now, I would put that on even though it is not rolling release, so I settled for Manjaro XFCE edition.
I had to get everything they do to work on Linux of-coarse, this coming from a Windows XP install. Most things worked 100%, they just had to get used to a slightly different look, and using Chrome vs IE, and Thunderbird vs Outlook Express. Printer worked out of the box, same with the scanner, webcam and pretty much everything else. Most of my time was spent getting a better looking theme than the disastrous theme from Manjaro.
Additionally, they also bought new hardware, so at least I had a clean PC to work with, brand new. The feedback I received is very positive, and I think Manjaro really makes Archlinux a dream to work with. The only time I needed the console was to install some AUR apps that can't be packaged on the small tmpfs /tmp. In hindisght, I should just have disabled that setting, or figure out how to get Pamac to use a different folder.
Personally, never having used Manjaro, only Archlinux, I am very impressed with how most work is done for you, and I still feel comfortable because it is 99% like Archlinux.
