My impression(i only really use openbsd)

Freebsd has the most developer resources and tends to be good at optimizing for speed but the userland always feels, it is hard to explain, but off, if you are fine with with the linux userland this will be a step up, openbsd, a step down. It has very good zfs integration and that is a solid reason for using it alone.

Netbsd just sits in the corner doing their own thing, I am not sure what that is but I suspect if I had not fallen for openbsd I would be using netbsd. A good solid small OS.

Dragonfly has an incredible main developer who has strong views about how parallel systems should be structured and the programing chops to pull it off. If you can take using a system with absolutely minuscule developer resources you will find real gems here, an amazing filesystem and very good multiprocessor support.

Openbsd strives for correctness above all else, speed tends to be a second class citizen, that is, if the developers have to make a choice between a simple obviously correct solution and a messy but quick one, they will almost always go for the simple one. speed is fine but not at the expense of readability. the system is probably the most full featured. With an emphasis on network daemons. but limited developer resources keep everything simple. I think of it as the best desktop system due to it's ease of administration and excellent ports system.

Portability, pkgsrc, some neat innovations, and a small and welcoming community. I'm not qualified to judge this, but they also value code quality and security.
