I have raced on my RSX and phantom 320, and bic Hybrid against RSX and techno 293. they are really not that different. The bigest variable I noticed is sail size. The next bigest is sailor skills. Then maybe sailor weight.
The boards do have performance differences in different conditions but not so much that you couldn't have a good contest and a good fun time. There is always handicaps to keep it interesting as well.
I think windsurfing is a victim of fashion. Most sailboat classes have suffered serious declines over time. If you enjoy competition for competitions sake, you better just go with what is popular at the time.
If you just like windsurfing then do what I do and sail your favorite board with what ever fleet is on the water at the time. Someone will see you out there and come and chase you around.
