OS choice

So should I install Gentoo or FreeBSD? I want a desktop OS that would be more professional and have greater coherence (packages working correctly and compatibly out of the box, no dependency errors) than my current Archlinux OS.
Thank you.

Well, as long as it doesn't depend any Linux system level crap. For standard C/POSIX sort of code it's usually just tweaking header and make files.
