Some people are enthusiasts that want to take the training wheels off and challenge themselves. I use CachyOS, which is Arch-based, because it thrashes everything else almost every time in speed tests. Thus far, it hasn't proven to be more complicated than the Debian-based distros I've used. I also wasn't expecting better features in Arch with certain programs. Being able to get the absolute newest version of a package at all times has proven to be much more useful to me than detrimental.
