They're both well put together, but the reMarkable is a clear winner. It's thinner, denser, prefers metals to plastic, and generally looks and feels like a more premium device. Due to the slim design, however, the reMarkable feels a bit more fragile. Fortunately, the reMarkable case is significantly nicer than the Supernote's. I also prefer the writing experience on the reMarkable, though they're unique enough I won't claim one is objectively better. (The reMarkable feels like writing with pencil and paper, the Supernote feels like writing with a ball point pen. Both are incredibly satisfying! We tried both, and I was planning to return the one and get us both the same model, but we ended up with different preferences.)
