I tried it out.  I hated it with a passion.  It did stuff that told me it was really inefficiently coded, and I found it almost impossible to use.   It's nice that it worked so well for you and others.  To be very honest I've seen some consistent issues with the work it produces that I'd rather avoid if I could, and I'd rather customize the topology more than it allows.  But then, I found Blender way easier to learn than Max, Wings, or Hexagon.  A chacun son gout. 

edited to say: I am very serious about to each their own, not being at all snide.  I do think it's great that it works well for others.  Maybe one day it will work well for me.  So far though, not at all what I wanted it to be.
