I tried every demo and free modeling app there is. I love the block modeling of Wings. I love the splines and curves of Shade8 standard. I then got into Hex1 which seemed to give me the best of both Shade and Wings. Hex 2 is a little buggy but has strong potential.

So. I use Hex,Shade and Wings. Modeling apps are very personal. I can't stand Truespace, I didn't like silo yet they say it is simular to Hex. That's why there are so many different modeling software out there.
