Strictly speaking, I would have to admit that Bryster's model is more accurate(but he had access to more accurate data)and he "went the extra mile" by adding interior details that Drac didn't. Drac on the other hand showed that if time is of the essense, Wings would have a much faster and more efficient work-flow. I love and use both apps. Each has its own strengths and weaknesses. Even though I was one of Drac's seconds on the "Field of Honor", I have to bow my head in Bryster's general direction and give him my vote. I hate to do this though 'cause his ego is already insufferably huge, and he keeps calling me a "Heretic".;-P
