That's pretty much it. A lot of the people I see using a BSD these days do so because they always have and they prefer what they know, which is fine, or they just want to be contrarian.

Realistically, aside from edge cases in hardware support, you can do anything you want on any modern *nix. There's not even as much of a difference between distros as people claim. All the "I want an OS that gets out of my way" and similar reasons apply to most modern well-maintained distros these days. It's more personality and familiarity than anything objective.
