Thats an interesting question.  It really depends on what you determine as secure.  For example people say Microsoft software is insecure.  In reality because its more popular more people attack and find vulnerabilities.

All of the operating systems you mention will have vulnerabilities.  Have a look at SANS storm centre for regular updates. http://isc.sans.org/

Can I ask what you are trying to achieve?  That way we can probably give you some more specific advise on what you need.

Hope this helps.

OK, I'll throw in my $.02, though it may echo a lot of the above.

If you're talking about the OS that will be the most secure out of the box with default settings and no patches, there is no question that it is OpenBSD.

If you're talking about the OS that is likely going to be the easiest to get to be reasonably secure and stay that way (keep up with patches, etc), and still get real work done, it's likely OSX.

If you're talking about the OS that you can lock down the very tightest, get patches for vulnerabilities as soon as possible (maybe even before official vendor patches are out), and still get real work done, it's likely (RedHat/SuSE/etc.) Linux, with Solaris 10 as a strong contender too.

Windows can be locked down pretty tightly, but a lot of things break.

Linux and Mac OS X would be the most secure of the two. Why? They tend to leave more ports closed by default... however, it cannot be said the operating systems are necessarily less flawed since MS is a bigger target due to the installed user base. However, XP SP2 did do a hell of a lot to improve on security flaws with the Windows firewall.

However, here's another thing to factor in: Linux is the least friendly as a desktop OS to most users

A lot of the other major points have already been raised, so there's no need to repeat their words.
