Well, I did a Firefly versus Poser 4 comparison (apologies for the graphic but I wasn't going for artistry).

I have to say, I'm impressed with this program. Despite the mega number of lights, Poser 5 rendered on (and I can't say that about all light sets I've tried). Firefly took longer to render, but Firefly always takes longer to render (for me). I have a wimpy Windows ME set up so don't think I have a super computer system to work off of. And I'm a techno idiot...if I can get the program to do anything, it's proof it's fairly user friendly (I'll admit, it took some playing to figure out what's going on but the help screens are good about pointing you in the right direction). I have zero experience with Python scripts, by the way.

Good job, Paul!
