Apple Integration Is Tighter
Apple Maps works with Siri and on the Apple Watch, but the tight integration between the mapping application and Apple’s other devices and products doesn’t end there. There are tons of other small ways that Apple Maps just works better in the Apple ecosystem.
One example: Handoff. If you’re at your computer and looking up directions, you can easily send those directions to your iPhone using the Continuity feature. It may only be a small time saver, but it will keep you from having to type in directions and find a location twice.
