No one can make the right decision for you. Decide by yourself and before making any purchase, check out all demos . If you feel most comfortable with one application, go with it. Regardless of odds and ends of other apps. In the core, the features are more or less similar, one prog is better for animation, the other for modeling tasks etc.
But what really counts is that YOU feel comfortable with your decision. It`s pointless having a powerful and expensive app, but the workflow doesn`t feel right for you.
