I'll choose the map system that actually works... maybe I'm alone but I don't remember ever being served an ad in Google Maps.

In my opinion the "Latest in the Area" screen using 30% of real estate by default when you launch the app is an ad, regardless of whether the businesses featured there actually pay Google or just show up there randomly.
