[Splines]

Google maps has ads, it's just not so in-your-face as Waze is. Search for stuff and depending on the topic the result list will have an item with a purple "Ad" tag on it (I searched for "tires" and got a hit for a tire store tagged as an ad).

I agree that gmaps has a better interface, at least for routing. I vastly prefer the alternative routes implementation on gmaps (it's right on the map). In waze I need to click through a few screens, which isn't practical when I'm driving. In gmaps I can glance at the map and make a decision without touching the phone at all.
