I use it on both, Mac and PC. Difficult question what is better. To be honest, very often i do the scene setting on the Mac and render the thing on the PC after. But that has to do as well with the fact that i am on a very old G4 that is not as fast as the PCs here in the office. I like the option that i can do other things while working with Vue. That is something that is much easier on Mac. The interface is identical. And the files are 100% compatible. So no worry in that field. To compare speed really is difficult because of the too different specs that machines normally does have. Vue, Infinite or Esprit is no island. It works together with other software too. Poser is a big issue. I personally would therefore go for the solution which makes it easiest to use the other stuff as well. A lot more to say but i expect this a long and heavy discussion so i think i keep some arguments for later.
