Contrast is definitely significantly better on the 12.9 inch, but turns out the better display quality isn’t enough to overcome the fact that the 11 inch iPad is just a much better size for the way I use my iPad (mostly in tablet mode out of the magic keyboard). I now plan on returning the 12.9 inch and will just wait for them to come out with mini LED on the 11 inch before I upgrade again. honestly I’m not even disappointed about it, if anything this experiment just reaffirmed how much I love my 2018 11 inch iPad Pro.
