I actually think the search feature rocks, because you have high fidelity OSM maps to query. Can't search for drinkable wells in Google Maps!
But then, it of course isn't Google Maps. It is likely to be more out of date and will not understand "natural" search queries as Google does. I believe it just takes some getting used to. There is overlap between the two, each service has its strengths and weaknesses, but also unique features.
+1 That, and it works in mountainous areas like the Alps or Pyrenees, where you're lucky to have GPS and most definitely can't rely on 4G for Google Maps
