It's currently unparalleled when it comes to realism as in realistic 3D reconstruction from the real world. Photogrammetry only really works for nice surfacic data, whereas gaussian splats work for semi-volumetric data such as fur, vegetation, particles, rough surfaces, and also for glossy/specular surfaces and volumes with strong subdivision surface properties, or generally stuff with materials that are strongly view-dependent.

This seems like impressive work. You mention glossy / specular. I wonder why nothing in the city (first video) is reflective, not even the glass box skyscrapers. I noticed there is something funky in the third video with the iron railway rails from about :28 to :35 seconds. They look ghostly and appear to come in and out. Overall these three videos are pretty devoid of shiny or reflective things.
