I got Bryce 5.5 about three months ago but didn't get much of a chance to work with it to learn it. Then Carrara goes on sale (sale over monday I think) and I almost didn't get it because I'd already gotten Bryce. But everyone said Carrara is better so I went ahead and got it. I can already see that it is better. And I don't think it's going to be hard to pick up since the interface is very, very similar to Bryce's.
