I don't have any experience with the remarkable, but i recently got a kindle scribe and it's better than the boox ereaders/tablets i've gotten over time.

The clarity, density and speed of the kindle's screen is miles better than boox, probably close to remarkable if the videos are any indication.

I got the Scribe for the large screen to read ebooks, but the pen and its responsiveness and feel is surprisingly good.

i don't know if it does handwriting recognition, but the notebook app has been surprisingly fun for me to jot down notes when i'm contemplating a design problem.
