I bought both the Remarkable Paper Pro and the Supernote Manta to try at the same time. It was no contest. The Mantas user experience was key. It is much more responsive which just makes everything smoother and more natural. The Remarkables delay and screen flash was just so jarring it didn’t feel natural. Plus, the Mantas ability to support multiple files and Kindle, it just didn’t make sense to stick with the Remarkable. What I would like to see is a more premium version of the Supernote, on par with the materials used in Remarkable.
