Honestly, the most widely used 3d package in the professional industry today is probably... drumroll please... ZBRUSH. Yep, Zbrush is used by every single VFX and game studio I can think of offhand, including Disney, ILM, and many more. In fact, regardless if the studio is using Maya, 3dsmax, Cinema4D, or whatever... Zbrush plays a huge roll in the production pipeline from start to finish. These days, all character models are done in Zbrush first, then retopologized and brought into the animation package. It's actually fair to say if you know Zbrush really well, and can sculpt well enough, you have a chance to land a job somewhere in the CG industry these days.
