Eh; testing doesn’t break THAT often. Having used it on many of my devices for almost 4 years, I can count on one hand the number of times it broke in a way I had to chroot in to fix it.
This is very unlikely to be because they are using testing.
Still, using Debian Stable is probably a smarter idea for this user.

Eh, I disagree with you on Pacman. It could be possible I was doing something stupid, but I’ve had Arch VMs where I didn’t open them for three months, and when I tried to update them I got a colossally messed up install.
I just made a new VM, as I really only need it when I need to make sure a package has the correct dependencies on Arch.
