ideal OS distro for network scanning?

[offset <offset () svcroot net>]

Greetings,

Looking for information on network mapping relative performance and accuracy between different
opensource OS distributions (ie. linux based (fedora, redhat), bsd based (openbsd, freebsd)).

I like OpenBSD's security paranoia (dont want the scanner being compromised), but I also
understand that linux can be hardened as well, so my second concern is the
underlying OS skewing the results of a network scan and the ability for the OS to
stay out of the way of the scan results.

Regards and thanks in advance.
