I agree that the author put a nice disclaimer warning us he will not be telling us why BSD is better - but he definitely mentioned that it is .
It is rather obvious the author is biased towards BSD - For example - "Chaos VS Order" and "Right VS Wrong" as titles when comparing BSD and Linux from a philosophical POV. Reading this reminded me of how I was as a young Linux user 15 years ago (Slackware 3.4...) and was proud of using a barely usable OS - blinded by my own pride arguing in favor of Linux without any true understanding of the internals - and unable to hold a single argument of what makes it any better.
If i wanted to sum everything i would basically be saying - Linux is different. But thats why Linux has many different flavors - It depends on what you like - and your level of expertise. If you like compiling everything - you could use Gentoo. If you want it to "Just work" - you could try out Ubuntu. If you need something Robust and supported - use RHEL. While it is true that Linux development might be more "chaotic" than BSD, there is order in the chaos. What seems to be unordered and unorganized in fact has its own way of making things play in harmony.
PS. I would really love if anyone has a more technical comparison of BSD VS Linux (FS, Scheduling Etc..)
