Almost a solid replacement
I came from using a windows phone and always preferred the keyboard on those compared to my iPhone. There are just a couple things that get me about this version of the keyboard on the iPhone.
I find myself pressing "b" often after words instead of the space bar, as well as hitting "." instead of space as well, which throws the word correction or suggestions through a loop. If this could be addressed, then it might be a game changer of a keyboard.
