Which 13.3-incher?

I will ( hopefully ) attend a Music Conservatory in the fall. I am saving up to purchase of an e-ink notebook for practicing music from PDFs and composing.

A 13.3-inch device would work best for me. I am thinking about the Boox Tab X C (color would be a plus for circling or underlining bars I need to work on). On the other hand, music notation would be, I am guessing, much better on the Note Max's paper-like feel.

Has anyone here actually written music on either device?

Thank you.
