Arch's goal of simplicity means there's usually one preferred way to get things done - through organized and well documented configuration files. This focus, combined with the community's recognition that configuration files can be intimidating, has resulted in excellent documentation that's accessible to newcomers, and very instructive about how Linux actually works. The documentation is often so thorough that, when searching for solutions to problems while using other distributions, such as with video card drivers, oftentimes you'll find the most effective solution in the Arch Linux wiki or on the forums.

Arch Linux follows a rolling release model, which allows users to stay on the most up-to-date versions of the software they are using.

If searching through the wiki or the forums for any problems turns nothing, any question on the official forums, Arch subreddit or the IRC channel will be answered within minutes. There will probably be no hand-holding however, Arch users prefer to point anyone to a resource that may help them instead of trying to outright solve their problem in a forum thread. This is quite helpful for people who want to really learn how their system works but also for other people who may stumble in that thread considering how most problems don’t have a universal solution.

There are extremely helpful 3rd-party installers such as Anarchy Linux (Formerly Arch Anywhere).

The process of learning to setup and use Arch will improve your skills with Linux and computers in general.

From latest wacom pads to obscure wireless cards in laptops Arch's hw support has been and continues to be good. It has worked on laptops where other leading distro's like debian/ mint/ ubuntu failed to detect and work with all hardware.

Arch is mainly aimed at experienced Linux users, there is no hand-holding and not much in a way of UI elements when trying to install or tweak settings.

Pacman has performance advantages over apt-get and yum in both database operations (thanks to being written for speed) and download times (by virtue of using better mirrors than other distributions tend to select by default). There are also fewer default repositories to download from, and all package management is combined into one tool instead of being split into dpkg, apt-get, and apt-cache like on Debian distros.

QoL of Arch is generally good. You get something more consistent and doable in Arch then you would get with most other OSes.

Arch does not come with an automatic installation process. The user is expected to walk through the installation steps published on the Arch wiki. This is very useful if, later, something happens to the installation as the user will be more familiar with the foundational steps required to get a full blown Arch installation working.

This distro is barebones enough to make a new distro from.
