I've used Cinema 4D, Lightwave, XSI and even Maya and as an all round package Carrara 5 Pro is really catching up with the big boys. I've also used Vue 5 esprit and Infinite a lot and when it comes to landscape work C5P leaves them standing in all aspects except ecosystems (instancing) and even that gap is closing fast. What C5P doesn't seem to have is all of the baggage that comes with the Vue line which is the biggest reason in my move to the Eovia stable. I've been extremely impressed with the beta we've been playing with for weeks and now I can't wait to get my hands on the final release :-D
