Yeah, I seemed to have forgotten that the iPad Pro features ProMotion, which makes the display smoother with action using the 120Hz versus the new Air going with the old 60Hz. This is huge if you've ever experienced ProMotion before with scrolling and action games and movies. Plus I hear that it makes a pretty good difference with the Pencil2 because of the much lower latency, so you don't get micro-delayed response to you drawing and shading. As far as "better chip" people are seeing that single command stuff like opening apps and simple things, it may be faster due to 5nm packing of transistors, but for complex or multitask performance the a12Z is still much better. The simple everyday user wouldn't notice and would be overjoyed with either, though.
