In my experience at the store, it was not a little better, but SO MUCH better texture-wise for the pencil. Somehow, with my hands and skin type, the nano surface is both less resistive (also a hooking left-hander) which is a godsend to my handwriting style, while at the same time being slightly more *textured* for the Apple Pencil. I've had iPad Pros since the first small version (9.7) with the Pencil and my handwriting looks IMMEDIATELY, vastly better with the nano screen.
I was blown away, and I feel like the narrative around this feature has been way off in the reporting. It was so good I returned my base model 11-inch glossy for a 1TB nano (on backorder 🙃) then and there despite the massive price increase.
Also, quite frustrated with Apple for not making this available on lower end (Pro) models.
