(No provocation)
I see these reasons:
- newbie
- lazy (don’t wanna edit config files etc.)
- unique features (like assistant/toolbox, some optimizations like in cachyos)
- wanna check how different systems are set up (that’s rather distrohopping)
Personally, I used manjaro i3 when I was beigginer and wanted to see how tiling WM should be configured (check out ranger config, for example). But after some time, I don’t see reasons why not to just customize pure arch (same with debian and debian-based distros).


I don’t use Arch anymore but I can imagine that the install process turned a lot of people off it or pivoted them to stuff like Manjaro, CachyOS, Endeavour etc. It isn’t until recently that ArchInstall has become VERY good and simple.
Primary factor even with Archinstall is if you’re trying to install Arch via Wifi. you have to do iwd and all that and for someone who isn’t quite as comfortable on the command line yet that can be daunting. Even now for myself if I were installing Arch I still have to pull up the Arch Wiki during install cause I can never remember the iwd commands for wifi. I’ve also borked the install a couple times because I either forgot to include the networkmanager or selected the wrong video drivers.
