I'm afraid these are subjective questions, and the only way to answer them is to try out the mini yourself. Try it in the store, and if that's not good enough, take advantage of the two week return period (if you live in the right area for that).
I bought the original mini for reading PDF documents, and for me it's brilliant at that. I typically read them in landscape, though I can read them in portrait. On the other hand, I have poor handwriting, and it helps me to have a larger device for taking handwritten notes (I have a 12.9" pro for that).
