Same, and lately paru is a close second since I started using it because yay was re-downloading things and paru has the option to 'KeepSrc'. Also my 12 year daily use Gentoo install got replaced with arch this past week to match everything else so Portage becomes a solid third place for me.
APK, the alpine linux package manager. It is very fast, faster than pacman and it blows apt and dnf out of the water and APKBUILDS are not too hard to write.
Docker. It's a bit incomplete (regarding available packages) but you can do some really effective stuff like making your command run as nobody or even turning off the internet completely, but just for that co---
---...ooooh. OOOOOH. Package manager. Please forgive my ignorance. Um...paru takes the crown for me, and nala if for some reason someone is pointing a gun towards my bun forcing me to use Ubloatu.
Definitely Nix, with flakes. Running on NixOS and Darwin.
Also flatpak,appimage-run,docker when I’m too lazy to package, or when I simply don’t know how to (e.g. electron apps,dotnet)
Yay for Linux because it feels like the easiest way to upgrade, search and install. Scoop for windows because it is sane, only user level permission, and is surprisingly up to date with a large catalog. Also easy to add new entries.
Currently I think that deb + flatpak is best combo. However with immutable systems become more mainstream that might change. However I do believe that flatpak will continue.
I like pacman/yay enough to the point that I'm hesitant to use any distro that isn't arch-based...
I was reinstalling Linux on my laptop a few days ago and was thinking about going for Fedora, but leaving the AUR behind felt like too big a trade off lmao I'm lazy as hell
So here I am with yet another install of Endeavour. I always go back to it.
