I think the most honest comparison is to download a demo and see yourself. I wonder why nobody else has proposed that so far. Too bad that there is no demo for Infinite available yet, too new. Regarding the models. Most you refer to are models for Poser originally. It is incredible easy to open Poser files in Vue, just use the original Poser format pz3. So if you have Poser you have access to an immense large database of models.
