I found this informative YouTube video (https://www.youtube.com/watch?v=8RqFL92IEYs) that gives good reasons why to use Arch.
The video wasn't biased as it's factual about what Arch is, its philosophy and what makes it different from other distros (distributions). It's fairly detailed but excellent even for Linux newbies.
It's from a couple of years ago; however, 95% of the information presented is still accurate. He describes many Arch-based distros, some I hadn't heard of before this video. But at least one of the distros no longer existed. And he mentions Ubuntu 17.04. :)
It's about 13 minutes long but it's well-worth watching if you're at all curious about Arch.
