The floor plan route with MVOs is symbolic projection in which grids will look better and since doors and windows are not projections you don't need to fight with the cutting plane that much.
The 3D Document version is a projection so symbolic control is limited.

It all depends on the project, but normally everything being equal I use the 3D Doc during Schematic and Design Dev and then switch to Floor Plan MVO during CDs.
