Not really. They have the same origins but totally different focus and have been apart for so long that they are substantially different. Though they borrow stuff from each other. And even Linux does (OpenSSH for example comes from OpenBSD). In general FreeBSD is a great allrounder with up to date packages. OpenBSD is very focused on security and it's pretty minimalist as a result though you can install what you want. NetBSD strives to support as many hardware platforms as possible so it's a good choice for that weird old server you found on ebay. They had more similar goals in the past but this is how they've diversified (at least how I see it!) Besides these focus differences there's also some personalities behind the different BSDs that make Linus look like a kitten :) So that tends to influence people's OS of choice as well. I don't want to get involved in that but I wanted to give the heads-up because it will come up in discussions once you start looking into the BSDs.
