I run multiple arch systems and multiple Debian systems in my house.

Debian is great if what you want to do, is something that has been easy for 5 years. You set it up and forget it.

Debian breaks down whenever you try to do something new that requires some new dependency. Oh you want to run a Go program written in 2023? Now you have to download and install the new version yourself because the latest version in apt is 1.19. On arch stuff like that is generally not a problem. It's the best supported distro after the Debian based ones.
