Well most say that Vue trees are better. I'd have to agree. I have both Vue 4 and Bryce 5, and the trunk and limb structure looks a lot better in Vue to me. Xfrog is an awesome program, its what I use. It's interface is really odd and most don't care for it though. I've never used OnyxTree, but everyone that I've talked to says it's a very user friendly interface. You catch on right away. It also comes at a much higher price too. I believe you can download a free trial of Xfrog. That might be something worth doing. Also check out their gallery for examples. www.Xfrog.com
