The only thing missing in the Samsung keyboard that I use is Arrow keys and when typing only numbers I like ten key. But otherwise I do like the Samsung's keyboard for GN2.
Mainly I use the arrow keys within SwiftKey keyboard that keeps me coming back to the SwiftKey keyboard. For me that is an important feature for a keyboard. I always miss the right spot with my big fingers.
