The problem with OSMAnd is the search feature is really bad and they are missing most addresses in many states (like Georgia)... I still use it instead of Google Maps but I often have to convert addresses to Lon-Lat using a 3rd party web service.
I am currently loading the location in google maps web and picking "Open in App" in the browser, but it doesn't always drop the pin in the right spot
A few months ago the voice navigation started speaking funny too, mispronouncing words (I noticed it when she said "We found a faster route, which saves x minutes"), but that fixed itself.
