If you do not tinker the system , and have nothing exotic installed from AUR, keep the system updated and take a look to the news here: https://www.archlinux.org/news/ if something needs attention, and simple wait some days with update, to let us/them solve the problem.
As @fernandomaroto says right: Using the LTS Kernel is a good option, as it will keeps version for long term (as it says) and you get rid of problems causing by kernel updates.
Using another DM is an option, but depending on your DE For GNOME you are on the safest side with GDM, KDE - sddm, but they can brake too, special on non-intel graphics.
So i keep a second one aside to use it if i get a failure on the other one, this do the job a lot of times.
My Kids and my wife all running Antergos on different machines, no system where broken for the last 2 years, daily work like Browsing, playing games, and such, weekly updates, without tinkering, keep them save!
[updates once a week] = [90% less problems]
