It's most known for its portability and the number of architectures it supports, which many interpret as a comment on the quality of its underlying architecture.
SDF runs on it so you can play with it there.
OpenBSD is known for its security but I've run into too many rude people in their community which has never happened to me with NetBSD, maybe just a coincidence.
FreeBSD is known for its performance and being more up to date with drivers, etc but feels more "messy" and therefore less BSDish to me.
Take all of this with a grain of salt, just one man's take.
