Note 8.0 note taking vs 2014 10.1 topic

So I'm thinking of picking up a Note 8.0, and would like to ask two questions before I do so.

1. Is the note taking quality (inking, lack of lag, etc.) on the 8.0 the same as the 2014 10.1 edition?

2. How is the screen quality on reading an ebook or PDF? Any pixelation?

Thanks in advance.
