The outputs of Photogrammetry are still more useable today for 3D work like importing the scenes into Unity and editing. NeRF's are great and getting better every week but the output is mostly a video camera fly through of the model scene. NeRFs will really start to shine once they have common rendering and useability in game engine pipelines etc.

In my experience NeRF tends to work better for objects that photogrammetry struggles with, like transparent objects. By using marching cubes you can also export scenes as a mesh. instant-ngp (https://github.com/NVlabs/instant-ngp) has done an amazing job of making NeRF accessible, but you still need camera positions from other software such as COLMAP.
