Your comparison is about right, but wanted to mention that the touch id on the Air 4 is on the power button, which was newly developed and debuted on this ipad. It works very fast and reliably, and takes you instantly to the home screen (no swipe up required). Also regarding the CPU’s. The pro has a 2 year old A12Z chip, and the Air has the brand new A14 chip which is the worlds first 5nm processor (same as the iphone 12). The A12z has 8 cores yes, but only give you 10% more multicore performance than the more efficient 6 cores in the A14. The A14 single core performance is 40% faster which is on par with the Mac M1 chip, so the Air will feel snappier than the pro with day to day tasks. In terms of GPU its about even, with some tests showing the A14 to be faster and others the A12z. Another benefit of the A14 is its neural engine for machine learning, which is significantly more powerful than the A12z. If you really want a Pro ipad, its best to wait a few months for the 2021 version which will have the A14x. Right now though, the Air 4 is the overall better value proposition in my opinion.
