Pro Best execution of save location feature
Recent updates have made it so you can label a place instead of being stuck with some address or GPS coordinate and forgetting what it represents. Saved places show as stars and are all on one layer as long as you're logged in. There is also the ability to create maps (parallel to groups) for things you might not want to see or have show up all the time whenever you're using google maps from day to day.
This feature is highly helpful for planning, even if you're a person who likes to wing it.
Pro Updated constantly
Nearby my house, there is major road construction in progress. Apple maps didn’t show this at all, but google maps did. There was also a new, small road that was finished around 3 days ago. Google maps shows this road. Apple maps still hasn’t shown the major construction.
Con Maps saved offline can easily wipe your bandwidth cap via auto update
Google Maps offline maps update automatically in the background. Not a problem if you're using a sim card in your phone, but if you connect to a pre-paid hotspot that the phone recognizes and connects to as a wifi device you risk burning through your data allotment. The offline maps can be set to update manually, but this is not default behavior.
