There's no doubt about it. FreeBSD is more secure and stable than Linux. This is by default, but it's also easier to make it even more secure. It's not better in every way though. Linux has a little more hardware support and more user-friendliness. But if you've been using unix for a while and aren't too heavy into gaming, FreeBSD makes a sweet desktop. I thought I was a Debian user for life, but once I got used to FreeBSD, that changed. I've been using it almost a year now. If you treat FreeBSD well, it will treat you well.
