Amazon - Kindle Paperwhite (12th gen) vs Kobo - Sage

The Sage edges ahead on the Mars Score (62.4 vs 69.6), but the 7.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Kindle Paperwhite (12th gen) if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight.

Pick the Sage if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are storage, screen size.

Both ship with comparable resolution, waterproof, color screen, so those specs don't separate the two — focus on the differences below.

Bottom line: the Sage is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
