Basically, you're looking for a boat with edges so you can carve in the surf, low enough volume that you can throw it around when you get hauling and bouncing, and something short enough that you won't hit bottom when you ride it all the way in (this is what usually happens if you get too eager when surfing your sea kayak in).
The Wavesport EZ-Big EZ-Super EZ-series is great (only difference is size). They are a little older, larger, and not quite as playful as the newest boats on the market, but they are good playboats and great river-runners. The ZG is the model that followed those; another great boat and a little better for playboating than the EZ. The EZG is the next one they came out with. Again a great river-runner and playboat but they've had issues with the cockpit rim cracking.
Hope this doesn't make your list too long, but these and the ones you listed earlier are all great boats. I would recommend going to the shop and sitting in all of them. From there you will be able to tell what you fit well in/what is comfortable and that will help narrow the choices down. Then demo the ones you like. Best of luck.
