Why choose TSDF method to extract mesh? Which method of extracting mesh is better?

Hello, since our supervision target is the depth map, we directly use the depth map for TSDF fusion to extract the mesh. From my personal experience, depth maps are more prone to noise and holes, and the geometric details are slightly inferior, but the extraction cost is low. On the other hand, extracting the mesh directly in 3D is more robust to noise and potentially offers better geometric details, but the extraction cost might be higher.
