Technical minutia aside, imagine the various operating systems as each having a distinct culture. From this perspective, selecting the OS to use is a matter of finding the culture that best matches your demeanor and style.
I see some of the various OS cultures like this:
- FreeBSD is like a university campus.
- OpenBSD is like a military base.
- Enterprise Linux (RedHat) is like a business park.
- Ubuntu Linux is like Disney World.
- MS Windows is like a shopping mall.
How do you see them?
