Bullet-proof Arch Linux install process

And for those who already know about this or just want to use Arch, there are many derived distros providing an installer (such as Antergos).
That said the installation process is not representative of the daily use of the system and I actually use Arch mostly because it "just works", with no major versions upgrades to perform every 6 months, no complex/fragile automation stuff that breaks regularly (looking a you apt), and no need to add a ton of unofficial repositories to get non-outdated software.
Anything that 'just works' has some magic behind the scenes, and that can go wrong. When it does, you don't have a clue. For most people, that's fine - they'll wait for the person curating the distro to fix it. For a power user like me, I'd like to be able to go in myself and do so.
For what it's worth, I've heard the same things said about cars. A lot of enthusiasts dislike modern cars because - despite being much more reliable and efficient, they are much more complex and hard to tinker with. If you know all about your car, you might be better off with something you can control, if you don't, you prefer something that 'just works'.
It's a matter of priorities and Arch developers don't see it as a useful effort.
Still haven't switched because I don't know enough Linux. But at some point I might.
If you want to switch to Arch, find an afternoon and switch. The wiki has a good starters guide. After you've run through it once wipe it and run through it again with everything you learned the first time through.
One of the reasons I settled on Ubuntu is AskUbuntu. It has a different standard toward questions, more like HN or StackOverflow, than the Arch community has traditionally been known for.
