Over the past few years I've been here, I bought Shade, Silo, Modo, and Hexagon. All have unique features and abilities. I also bought Pegasus to try it out, after reading about the neat features it does offer. I do most of my work in Hexagon, but I like the way you can create low-poly UV maps, and when you subdivide the mesh, the UVs adjust accordingly. I also like the way I can set materials, UV groups, and mesh groups, without disrupting the mesh. I'm sure that this can be done in Hexagon and other apps too, but isn't as intuitive. I'm a tinkerer by nature and enjoy neat little things, hence my Poser addiction. As for Pegasus, I think that it is a great simple yet powerful modeler for those who cannot afford Hexagon, C4D, Modo, etc. I also recommend it as stepping stone approach to larger and more powerful programs. I hope this helps, -Starkdog
