Not OP, but it's decent.
If you're used to swiping to type on Gboard, the predictions aren't as accurate. 10-25% of the time, manually typing is faster than swiping because the predictions are so wrong, or because there's no prediction at all.
It's supposed to train locally in order to improve the predictions, but I don't know how long it will take for it to "catch up" to the swipe-to-text experience that I'm used to.
As a non-technical person at the bottom of the learning curve, I can vouch for its steepness.
