I would say Avistar 51%, SuperStar 49%. I have a Avistar and it flies really good. As for the Super Star, one of our newest members has one and it flies really well, just it had more diedral and a flat bottom wing (as others mentioned). Both are also very durable. I stalled my Avistar and the rubber bands snapped through the wing and made a big hole but it was easy to repair. I have pics of that if you want me to show them.

Hope this helps
