I have the large iPad Pro and I just do not like the Apple Pencil.
It is cheap feeling, I think the way it charges is stupid and kudgy,I don't like its length or barrel diameter.
I don't care about the side shading feature.
I have been using the Adonit Pixel, now, with my large screen iPad Pro for about 5 months or so.
Adonit makes very well designed stylii.
The Pixel is made of machined and anodised aluminum, instead off cheap feeling plastic.. I like the barrel length and diameter better.
I like the way it charges much better and I like having the programmable buttons, just like on a Wacom stylus.
I just think Adonit stylii are much better designed, all around, than what Apple did with the Pencil
