Everything about using Android on Google's phones is better.
Since Google makes Android, its phones always get updates faster than anyone else. And since Google makes Gmail, Google Maps, Google Calendar, Google Docs, and all the other Google services you probably already use, you'll be delighted to find out how tightly those services are tied into the operating system. Imagine if all the Apple versions of those apps on iPhone — Mail, Calendar, etc. — were actually Google's. No jumping through hoops with two-step verification, or weird disconnects between your actual Gmail account and the version you access through Apple's Mail app.
As Apple might say: It just works.
When those services tie into Google Assistant — Google's equivalent of Siri — the experience is even more impressive. Assistant will warn you about upcoming Calendar events, and changes to flights, and traffic up ahead.
