Arch's default repos are definitely missing several cross-platform (at least Mac and Linux) programs that I've installed with Homebrew, without having to touch the config or add any extra repositories. I listed a few in another post, above. I've yet to see the opposite, because I simply haven't encountered anything I wanted that wasn't on homebrew. More details in another post elsewhere in the thread.

Arch does seem to be about as good as Gentoo's portage, which is the best selection I've yet to see in a Linux package manager. I'm not interested in a rolling-release base system anymore, though, because I just don't have the time or patience for "running update broke X/Wayland/audio/wifi/boot" these days, or fiddling with whatever it takes to keep that from happening. Rolling release applications? That I like.
