I was scared too and found out that it's actually the opposite !

I'm using Manjaro (derived from Arch), so I can't talk for Arch itself but so far (2 years) it's been way more friendly to me than Ubuntu (which I used for 7 years before).

Long ago manjaro was my favorite distro because it had a lot of great defaults that are rare among distros. The thing I didn't like was always having to be on top of updates or the update system would break and fixing it was a process. However, the thing that made me stop altogether was that one update caused my Keyboard to stop working!
