I'd take Nokia's Here anytime instead of Google Maps (offline maps alone are worth it). Also, I honestly don't understand a logic behind crediting something as complex to a single person ("a hero") -- "S. Jobs created iPhone", "M. Mayer created Google Maps" etc., there were whole teams of smart people working on these projects, I'm sure they would have been fine with any other reasonable leader and enough resources. The key point of technological success is the right time and place, so Google Maps were successful mostly because there was a huge need for them during smartphone and cheap cellular data surge, M. Mayer just happened to be a leader then and did her job (just as probably hundreds of engineers and lower ranking managers).
EDIT: Seems like my knowledge on Google Maps is a bit dated as I stated Here's offline map capabilities as an advantage. Still, the point stands and I still use Here as my go-to maps.
