I've been really impressed with out much Apple Maps has improved. I remember when it first launched I had Waze and Google maps on my phone since I would need to fall back to them often. Haven't had to do that in a long time now
Most recently, I was in Georgia (country) and navigation of any kind is nonexistent. Like often times I would look something up and want walking directions there but it simply isn't available. Google Maps worked great.
Google Maps looks like it supports combining public transit and bicycle, since you can select bike as a connecting mode to/from public transit, but then it never proposes bike routes. Apple Maps doesn't pretend to be able to do this. It is annoying, because mixing and matching bike/bus/train is a very common way of getting around in the DC area.
