The 12" screen and the better digitizing pen. My application is much more notes/sketch focused. I've got several different stylii for the iPad, none of them is as nice as the Note's pen. I like the larger size so that I can see more of the sketch even while zoomed, I don't care about having it in my pocket. The contenders were something like a Yoga 2 pro, the Note pro, or something from Apple. They don't have anything in that space so for that reason, they're out.
