Somebody has never used opensuse. Zypper is an amazing package manager, one of the best on any distro.
It can handle flatpacks, native packages, and packages from the opensuse build system, keeping everything updated and organized.
Pacman is very basic by comparison, and a lot slower too in my experience.
I guess I’m smart enough to install opensuse, but dumb enough that I somehow got slow pacman.
I kid you not, on my hardware zypper is the fastest between ubuntu apt, fedora dnf, and arch pacman. dnf was the second-fastest on my hardware, with apt and pacman being pretty sluggish
I’ve also used portage which was even slower, but probably not a fair comparison considering how much more complex it is.
