Sync with H3 and paper like

Hi,
Does the tablet work well with the H3 pen? (For college use and writing-a lot).
Is hi9 plus more relevant to the study? Better sync with the pen?

Another thing, I didn’t find a “paper-like” screen protector, is there a model that can fit one of them? (Hi10x priority), iPads and Surface with very different sizes.

Thanks,
Eliran.
