Probably the best comparison yet.
Interesting to see that the video exports took 14% longer on the Air than the Pro. Not a big deal, but I wonder why.
I didn't know the Air was limited to USB 2. I can confirm I can get USB 3 speeds out of the iPad Pro 10.5" with the Lighting to USB 3 adapter, using a USB 3 flash card reader. Also, it should be noted that I had issues using that USB 3 flash card reader on my old USB 2 iPad Air 2 through that Lightning to USB 3 adapter.

When I switched to a USB 2 flash card reader on the iPad Air 2, the issues went away:
iPad Pro 10.5 --> Lightning to USB 3 Adapter --> USB 3 card reader --> UDMA CF = Works, fast speed
iPad Pro 10.5 --> Lightning to USB 3 Adapter --> USB 2 card reader --> UDMA CF = Works, moderate speed
iPad Air 2 --> Lightning to USB 3 Adapter --> USB 3 card reader --> UDMA CF = Doesn't work or VERY slow
iPad Air 2 --> Lightning to USB 3 Adapter --> USB 2 card reader --> UDMA CF = Works, moderate speed
I wonder if those issues could occur on the Air 3 like they do on my Air 2.
In the review he states that games will be faster on the Pro, but that's just based on the Geekbench Metal score it seems. They may be in some games, but it should be noted that some games are faster on the Air than the Pro in other reviews. I'm not sure those who tested the games limited the Pro to 60 Hz though so that could be a factor.
