Thanks for championing ODM! :) It's true that proprietary systems have had a lead in development for a long time, but especially of late the software has gotten really good. If you haven't tried the software in a while, I'd recommend updating and giving it another try.
The quality issue is an interesting one; I remember having a discussion with a client that was considering transitioning away from Bentley's ContextCapture (CC) and they mentioned that CC was generating much denser point clouds compared to ODM. CC tends to generate very good looking point cloud models, except its algorithms extract points from a mesh interpolation approach, so sometimes you end up with points where geometrically there shouldn't be any. Sure they look good, but is that "good" quality?
