(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).
Arch elitists don’t want you to know this but you can just type archinstall and a text installer guide thingy will install the system for you based on what you tell it.
That said, you’re spot on on the last part. I love arch exactly because it is the easiest one to customize the way I want to but it’s not for everyone and not everyone should use it
