Security of the FreeBSD kernel

Hallo everyone,

I'm with FreeBSD for some years now, I'm still not yet an expert in it, I just use it on my servers, never tried it on desktops, so my experience isn't that good, and that's why I'd like to know what do you think about this test(s) of the FreeBSD kernel vs Linux vulnerabilities:
Would you agree with that? What are your thoughs? Is he joking or whatever? Are these reproducible? Is it more secure than Linux?
