I installed Arch after not using Linux for over a decade (last time was Ubuntu circa 2010). The wiki is excellent. The key here is you have to be prepared to put in the time to learn it all. It is rewarding. A lot of "learning" I end up doing with software & computers generally is how to use some proprietary thing and the knowledge becomes outdated within a year. The knowledge you pick up installing Arch will stay relevant for a decade or more and is worth the investment, and a lot of the minor issues people complain about with Linux become trivial things you are more than capable of debugging & fixing. I would not say installing & configuring Arch was particularly difficult on a technical level. It is simply a matter of accepting the time needed. It took me about three weeks to get my setup to where I was happy with it, although this is probably longer than most because I had to debug some lin/win dual boot network card issues.
