Sorry, Apple Photos, but I'm leaving you for Google Photos

When Google Photos launched two years ago, I installed it for one very simple reason: to backup all of my photos and videos to the cloud. It was a second home screen app on my iPhone, not yet worthy of being on my main home screen with Apple Photos. I'm not sure when it happened, but it did. And lately as I've fallen more in love with its growing features and intelligence, I've been wondering why I even need two photos apps on my home screen. One is enough and I'm finally ready to make it my default photos app.
