A lot depends on what you are used to. I have Hexagon, but I never managed to get into it. I find Wings 3D works pretty well, and it's free. There's some types of model it looks to be able to make without very much difficulty, others where you have to get used to how the program can best handle the work. It's not always obvious when is the best time to do a particular part of the job. But I'll be keeping an eye on this product.
