In many cases the MVS approach is more automated and usually requires no parameter adjustment, no extents / trims, and no selection of photos to process. The MVS method works best when there are a large number of overlapping photos. DSM processing will create a single Cloud/Mesh based on the photos in the project.
You can set the Meshing steps to triangulate the point cloud, either as a step immediately after DSM creation using the Meshing tab of the DSM dialog, or you can run the Meshing steps separately using the Modify Cloud/Mesh tool after the point cloud is generated.
