Trash. I mean, in some ways it's better than Apple's keyboard, but what makes Gboard so damn good on Android is, it does things iPhones don't allow. Gboard on Android associates your typing with your account and how you type and the kinds of things you say. Apple does not allow Gboard for iOS to get that information, and it doesn't run as fast or as efficiently as the iOS keyboard. I don't feel comfortable using any third-party keyboard. It's like using a keyboard on top of another keyboard. I feel the delay.
