(hope this is the right forum)

I have always been fascinated with city planning and urban design. I like the idea of designing towns/subdivisions/cities. Problem is, I don't know what software to use.

I work for a company that uses a ESRI and Autodesk products such as Map, Land, Civil and a bunch of others I can't think of right now.
We've got extra licenses and computers so that's not a problem. The problem is everyone I ask is bias towards their own product.

I've been reading product information at both ESRI and Autodesk sites but I'm having trouble differentiating between the autodesk products.

Is Civil 3D the best option?

Look forward to your suggestions and thank you.
