I don't claim to be the representative for Carrara and Hexagon, but I would invite anyone interested here to visit my gallery. I was a diehard Brycer until I got frustrated with the models I could create with it and the landscape limitations. I gradually switched to Carrara about 3 years ago and I can honestly say it was great decision. I also learned to model in Amapi (also Eovia) and then Hexagon. In my gallery you can see vehicles modeled in Hexagon and landscapes done in Carrara. For anyone using Bryce, I would recommend trying the 5.1 Carrara demo.
