Did you try the new Bing Maps?
Since I've been using Here maps from the get-go, I may have missed this - but now with cortana and stuff I had to use the default bing maps to add places. Just opened it recently to check where cortana had added as "home" and "work" and OMG it's 3d now with 3d buildings etc.
Very pleasently suprised.
Also, the data from Bing maps seem even better then Here maps for my area (Turkey / İstanbul) EXCEPT POI stuff. So, there's that.
Also seriously bummed that I have to re-enter all my places in Bing Maps so cortana can see them. At least give me the option to import my list from here maps (which is, tbh, huge).
Hits and misses, but mainly hits.
