But by far Arch's best asset is the Wiki. The Arch Wiki is a godsend: a large repository of documentation on just about everything you'd want to do, complete with instructions for the most common cases. Want to do a basic install? Go look. Want to configure pulseaudio (why you would, I don't know)? It's right there. Want to encrypt your disk? pick your poison, and get to it. X? Check. 3d cards? AMD or Nvidia, proprietary or open, if there's hangups, we'll tell you how to fix it. Games? From steam to just about anything else, there's documentation for getting then running.
There's a reason many arch users will tell you to RTFM if you have a question. But if you've done that already, the forums are quite helpful.
The only snag is that systemd is installed by default. However, like everything, the wiki has docs on how to switcg to another system, like sysvinit or openrc. Even more luckily, some very kind Arch users have gone above and beyond that, and created a repo with most of the openrc initscripts, and forks of necessary packages that are without systemd. These instructions are better, and can be found at http://systemd-free.org, under 'installation' and 'configuration'.
