I tried using Apple Maps on my iPhone to navigate to WeWork in San Francisco last week and it sent me three blocks off target with the exact street address entered. I switched to Google maps to find it correctly with the same street address. YMMV, single data point and all that. I've also used Google directions going through Los Angeles (from San Diego to San Jose) and it told me to exit the freeway for some reason in Los Angeles and get back on, which I followed blindly but wasn't too bad a diversion.
