What type of modeling? Free form surfacing, mechanical assembly modeling or basic shape creation? Most industrial designers that interface with mechanical engineers prefer solidworks. Higher end applications creo and catia. If you're doing basic stuff autodesk may provide more tutorials and an easier path to learning.

Solidworks is pretty predominate in my region which is in the great lakes region for most small to mid sized companies and easy to use. It's parametric features are handy when doing assemblies where geometry of parts may change but clearances and relationships between features needs to be constant or equation based geometry like gear teeth. It would bemy reccomendation for a solid mid-level modeler.
