I tried that after already having about 2 years experience with Ubuntu desktop and an Ubuntu server (but still mostly a Windows user). I’m also a software developer.
And I failed to install Arch on a laptop the last time I tried it out. Ubuntu ran flawlessly, trying to go step by step through the Arch installation I hit a random error (at a step that was very straight forward and easy in the documentation) and got stuck. Messed around with it and at some point gave up.
I mean that’s years ago, it probably works a lot better nowadays and especially on more modern hardware, but even so for someone new to Linux I’d never tell them to go with a do-it-yourself install. Slap Ubuntu on that bad boy, let them install a few packages, do a handful of terminal commands and they’ll get much farther. Instead of giving up three hours in because a random command (that they still don’t understand) is broken.
