I use both. Osmand+ allows me to contribute way more efficiently with PDIs and GPS traces as well as editing existing features, but when I want to navigate, I prefer Organic Maps. I also like more their rendering since it’s faster across all my devices. They are both useful apps. My main gripe is with the data in my area, as everyone uses Google or Apple’s data we struggle with contributors.
Chrome itself is rated 4.1 in Play Store, while Firefox is rated 4.6. Google Chrome dominance, at this point, is a consequence of monopolistic practices and not user preference. They are now using their predominant position in the browser market to apply ad technologies that their users rightly didn’t ask for, and they don’t like it.
