Arch offers the most packages, bar none. You have the excellent base pacman package-system, and then you have AUR, which is easily sanitizable. You can quickly verify that even things from AUR, in Arch Linux, won't do anything fancy in a bad way. Thinking Debian and *BSD has more packages than Arch is retarded. And once you AUR something, could be anything, and, everything is easy to verify not doing any shenanigans, then the final built package is handled with the internal Arch Linux package system, ie pacman.
