The screens are brighter overall at their max and now have adjustable warm lighting, but only the Signature can auto-adjust that brightness to your surroundings-we think that should be standard across all models. We tried the Signature Edition ( 8/10, WIRED Recommends), but all three have bigger, 6.8-inch screens with smaller bezels. The Paperwhite went from one e-reader to three that now rival the more expensive Oasis.
