Inventor vs Zbrush: Which is best for you?

powerful iLogic feature that simplies repetitive tasks

Assemblies always seem difficult, wither mating physicslly or with rules it always seems glitchy and I havent been able to grasp it fully. Despite this I am able to assemble my parts but I can tell the relationships are not full.

Even though it is intricate, there are SO many tutorials from the application itself to teach you anything you need - I especially love the custom user-interface, super accessible and helpful.

the learning curve is very steep. But also the fact that it is not possible to do rigging or animation on Z-Brush can make it less effective overall than other 3D modeling software that is efficient in all its other areas.
