Using Archlinux presumes you already know your system intimately and have taken the time to hand-craft it. That would make solving problems down the road much easier.
On the other hand, if you're like me and you want to just drop standard-issue Linux (i.e. Ubuntu) on a computer and then just use it, you quickly encounter gaps in the defaults/automatic setup and have to dig in and try to figure out where things went wrong. Your graphics driver gets confused when you plug in a second monitor. Your WiFi card isn't detected. There's no sound. Little things that kill your workflow in a death by a thousand cuts.
Windows has just as much intrinsic fragility, if not more, but through sheer economy of scale nearly everyone's real-world problems have been addressed by layer upon layer of defaults and automatic checks. That's how Windows manages to "just work" most of the time.
But it's actually also amazing how when you reinstall Linux, and copy over your home directory, everything looks like it was before and you can just continue on as if nothing happened.
Linux (at least Archlinux) doesn't require much once you install it, are happy with the set-up and regularly update it.
Unless you're the kind of person who likes tweaking their Linux and trying out many distros, but if you do that means you like fidding with your system :) I personally just like an Archlinux installation that stays stable for 5+ years and actually use it.
