All the BSDs are great. Most people tend to associate the following things with these three flavors of BSD:

• NetBSD : Runs on almost every architecture imaginable
  
• OpenBSD : Based on NetBSD, with high emphasis on security and buglessness.
  
• FreeBSD : Developed mainly for the x86 platform (with ports in the works for sparc and alpha); provides excellent speed and stability.
  

It seems that most x86 users find FreeBSD the best choice for them. But depending upon your needs, NetBSD or OpenBSD could be your solution.
