(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’ve ran vanilla Arch multiple times in the past, and each time it was for the 'fun’of building out my system, this was mainly back when I was a uni student.
These days however, I just want something that works well for my use case.
