Blenders easy to learn. The design aspect of it anyway, Beta is alittle Bit iffy considering everythings changed with it.
Blenders superb (aslong as you dont get the beta) apart from the fact theres plenty of online tutorials on youtube. Its well documented and you can come up with some decent 3D models.
I suppose it depends on what you want the model for exactly.
If its something important. Then id invest your time in blender. If its something quick and little then go for one of the other programs.
