I might be the odd one out, but I primarly choose a distro based on applications; while everything else (sudo, su, permissions, package management, administration, security quirks, etc) is secondary. It’s for this reason I settled on Manjaro for my computers.
If it wasn’t for the AUR, I would likely still be using openSUSE and/or Mint, resorting to the PackMan Repository and PPAs, respectively.
I’m not a fan of the “version freeze policy” used by Debian and distros based from it (e.g, Ubuntu, Mint), as it’s really arbitrary for most software (with exception to critical and flagship packages, such as the kernel and libraries.)
It’s not uncommon to be on a “stable” LTS version, such as Ubuntu 20.04, and be stuck with buggy software in which the upstream developers have fixed the issues, yet the package will never be in the official repositories because, heaven forbid, “version 3.0.5 is a higher number than 3.0.4!” (Even though the bug is fixed in version 3.0.5!)
How this is considered “more stable” and “safer” is beyond me. Luckily, for rolling release distros, such as Arch, Manjaro, and openSUSE Tumbleweed, you inherent upstream bugfixes (for all software, not just “crucial”) simply by keeping your system up-to-date without having to resort to PPAs, Flatpacks, abandoned repositories, and so on. (Not to mention the fact that the latest version of said application might not even exist in an official PPA!)
"The package system format (.deb, .rpm, .zst) is a moot point as long as the availability of software is within reach, such as using the AUR. There’s a good chance your package either exists in the official Manjaro / Arch repos or the AUR. Just because some websites offer an installer in .deb format, doesn’t mean Debian- and Ubuntu-based distros have the widest availability of software in the world of desktop Linux.
