Mudbox :: 3ds Max Workflow Concepts

I want to understand the theory behind the workflow between 3dsmax and mudbox.I know that exist 2 workflows:

1- send your low poly obj model from 3dsmax to mudbox, then subdiv the mesh in mudbox and generate the textures and normal map. Finally return to 3dsmax but ONLY use the maps to recreate a high detail model. This is useful when you make video games character or when you animate the model

2- send your low poly obj model from 3dsmax to mudbox, subdiv the mesh, sculpt paint, generate maps and return the HIGH resolution MESH to 3dsmax(return with textures). It works only if you generate still images, not animation.
