Did I get your attention?
I actually used Ubuntu as my very first Linux Distro. Now after using Arch, I can't imagine going back to Ubuntu. I've tried using it and other derivatives of it. And I find it very hard to use.
Yes installing Arch is harder...much harder, but after that everything is just easier to use. Especially installing programs.
I don't even use a Desktop Environment. I just use a simple i3wm and I can imagine using anything else anymore. I tried other DEs and just can't get the feelings.
Update: Arguing about stability is a weak argument. You do not have to constantly update. Just because you can, doesn't mean you have to. + if you installed Arch (vanilla, not manjaro) on your own you pretty much know 99% of what is going on with your system. You will know how to fix things.
If you said you used Arch, but was actually referring to Manjaro, then you really
can can't say you are an Arch-user.
