Radian. It's just so easy to fly that you can actually have fun seeking thermals rather than flying the plane. It is such a good package too. Personally, I would not get a Cularis. I was originally going to, but for hardcore thermal flying, the Radian is just a better plane. The Cularis is heavy which makes it fly faster, and it's not gonna thermal as good. Your gonna have to actually fly the plane to where you want it where as the Radian is a slower, more stable platform. People do like the Cularis for FPV though. Just my thoughts. I only own a Radian.
