Start with whatever you like. It's not that big a difference - they're all going to be difficult for you as a beginner, although some will look a lot more complicated than others.
All of the skills are universal, just start doing something. that's the most important thing. Are you doing 3d now, or are you being worried about what to start with? If you're worried, Blender is free, you're not going to gimp yourself, and you're going to learn the specialist software later, anyway.
