Full strengths for COLMAP
It covers the whole structure-from-motion and multi-view stereo path in one program, with both a graphical interface and command-line tools, and it works on ordered and unordered image collections.
Several capture methods including photogrammetry, LiDAR and Gaussian splatting
Can scan shiny and transparent objects

Full limitations for COLMAP
Reconstruction is slow and wants a capable GPU, and the quality of the result depends heavily on how carefully the source photographs were shot.
LiDAR features need a LiDAR-equipped iOS device
Processing relies on the service rather than your own machine
