We sued HERE API at a previous gig I was. We used it for standard geo-coding (also after Google starting asking high prices to use it) and the quality was very good.
In America, it is considered polite to exchange suits and countersuits prior to engaging in business, similarly to laying down a friendly barrage of suppressing fire when entering a room.
