Please don’t use manjaro: https://manjarno.snorlax.sh/

I recommend endeavoros if you want something arch based that’s pre-setup and configured.

But debian has a very diffferent usecase from arch, everything is kept up to date in arch, if you need recent versions of things, don’t use debian.

If you want things to not change, like on a server, or a workstation machine where you can’t risk a change breaking something, debian is great!

For gaming, i’d pick arch any day because gaming stuff is changing so fast. It’s also better for wayland since that’s also changing quickly.

Fedora is somewhat inbetween.
