Thank you all for your input and feedback. As an aspiring scholar, my end game desire is to learn as many of these programs as possible.

Nah, what I wanna make is for my own personal use.

They're legal. I'm a student at Full Sail University Just started a degree in Computer Animation, but I wanna start makin' stuff now, rather than later.

I'm sure there are some threads like this, but here goes.

I'm looking to learn how to make mesh objects and rig them for avatars. I currently have Maya, 3DS Max, ZBrush, and Mudbox. I know absolutely NOTHING about any of these programs. What I wish to create isn't very complex, but WILL require rigging.

My question is this:  Which is the most user-friendly for somebody as inexperienced as myself?
