it all depends on the preferences of the modeller. Personally I use studio max 6 for the clothing mainly because I find the boolian operations easier in max. Props I do in lightwave 7.5 because the modeller has better precision tools such as bandsaw. For characters, I jump to cinema 4d 8.5 because the nurbs options are great to work with and it has a super fast renderer on slow systems. I know all of the work can be done in one program, but again, modellers preference, I like to have different options available to me. p.s I put my vote in for wings 3d as well, exellent program for the price, also blender is a good program, though its harder to learn the interface.
