Zypper has the best UX of the CLI package management tools i've tried, at least as far as updates and installation come. My favorite part, which is minor and yet makes finding packages you might want to keep an eye on when updating, is how it highlights with a color the first letter of any package to be installed/updated/etc. It was a "why don't other package managers do this?" moment the first time i saw it.

(ok perhaps other package managers do it nowadays, but i installed openSUSE 2-3 years ago and i haven't really tried every package manager out there - mainly apt/apt-get and pacman as it comes with msys2)
