In the past two weeks, I've reviewed both the 7.8-inch Supernote A6 X2 Nomad and the 10.7-inch Supernote A5 X2 Manta, two e-ink note-taking devices so well-built and smartly designed (by Ratta, a privately held company based in the U.S., Japan, and China), they made me entertain throwing away all of my paper notebooks and embracing a fully digital future.

But I was sent both of these devices to test them out. If I was purchasing one for myself, which one would I buy? While they are perfectly matched in terms of their specs and capabilities, the answer isn't quite as simple as just choosing between screen sizes (or the $160 price difference).

If you're on the fence, here's a rundown of the (few, but notable) difference between the Supernote Nomad and the Supernote Manta—and my recommendation for which one you should by.

If you want to know everything the Supernote Nomad and Supernote Manta can do, you can read my reviews of both devices. But suffice it to say that, as noted, in terms of (most of) their specs and capabilities, the devices are identical.

Both Supernotes use the same Carta 1300 display (with a key difference I'll outline below). Both have a 300 dpi resolution. Both have the same RK3566 Quad-Core 1.8 GHz processor, the same 4GB of RAM, the same 32GB of storage. They run the same software and do all of the same things.
