I agree 100% with your second paragraph, and understand the frustration, but this isn't an instance of that. From what I've seen online, the most praise for OSM comes from European countries, where it seems to have better data than even the Google/Apple offerings. It has pretty good data here in India too, surprisingly good in some parts, pretty weak in others. But the main hypothesis holds - out of the many open source maps apps I've tried, Organic Maps is the one that sucks the least, in terms of usability, performance, robustness, etc.
