Kobo Libra Colour wins on color capability and physical controls, delivering 300 ppi Kaleido 3 output and 32 GB storage versus the Paperwhite's monochrome 6.8-inch Carta panel and 8 GB (per Kobo and Amazon product pages). The Paperwhite retains an advantage in battery endurance for pure text. This is a close call only if color content is irrelevant.
