Both can produce a 3D model. But they get there in completely different ways, and that difference matters more than people think when you're scoping a survey.
LiDAR sends laser pulses and measures how long they take to return. It can punch through gaps in tree canopy to capture the actual ground underneath, works in low light, and gives you highly accurate elevation data, which is why it's the default for terrain, forests, roads, power lines, and engineering surveys.
Photogrammetry builds its model from overlapping photographs instead. It needs good, consistent lighting, but in return you get realistic, colour-rich 3D models, which makes it a strong (and usually more affordable) choice for buildings, construction sites, monuments, and visual documentation.
๐ง๐ต๐ฒ ๐๐ต๐ผ๐ฟ๐ ๐๐ฒ๐ฟ๐๐ถ๐ผ๐ป: LiDAR measures the world with laser pulses. Photogrammetry reconstructs it from photographs.
Neither one is "better" - the right choice depends on what's under your canopy, what your lighting looks like, and what your deliverable actually needs to show.
