Those are all inferior substitutes. None of them can reroute you on the fly to avoid a major delay, and none of them provide real-time traffic updates on par with the updates provided by Google Maps. Being extremely popular gives it a huge advantage that none of the other map apps enjoy. There will never be a substitute because there is no logical incentive for anyone to use the inferior map apps, and without a massive increase in users they'll perpetually remain less accurate. How many people are willing to risk sitting in traffic unnecessarily to prove some point about not relying on Google technology?
