I wish they better documented their specific benefits and short comings.

I find COLMAP has better dense depth maps, a more configurable pipeline, is cross-platform, the code is solid, and the accompanying research is principled (it takes a Bayesian approach to stereo matching.)

What aspects of these make them great alternatives in your opinion?

I wish I knew! They are all on my list to try, that's all for now. :)

Got it. If you’re just listing open source photogrammetry software, there are many more you can add, e.g. Regard3D, OpenMVG.
