I know it was trash when it came out, but Apple Maps surprisingly seems to often find significantly shorter routes than Google. Google Maps always tells me to go to the nearest interstate while Apple Maps seems better at recognizing if a local highway is actually faster.
I have to double check the routing on both to make sure they are not making me go through 20 traffic lights to have a 10% probability of saving 45 seconds and 90% probability of wasting 2 min.
