It's so blatant from the very first second - everything is running at a level so much more smooth than any other device out there (gaming monitors excluded, of course). 120hz is the real deal. I'd read that some compare it to Retina vs non-Retina for Apple displays, and the comparison is incredibly apt. My. Goodness. Rotation is so smooth, scrolling is unbelievable etc. With my 1st gen iPad Pro 12.9 right next to the second-gen, it's painful to use the original Pro anymore... Great stuff. Great, great stuff. Well done, Apple.
