I like using my iPad better than my RM2 for similar reasons (I have both, but really only use the iPad anymore). The pickup is much better on the iPad, in my opinion.

However, one thing that I think makes the biggest difference is adding a screen protector. I particularly like the ones from https://paperlike.com/. It adds a layer that makes it less like writing on glass and more like writing on paper. For me, this was the biggest increase in usability for taking notes.
