I like the added point about the ease of customizing Kobo devices. Having recently tried or bought 2 Kindle and 2 Kobo devices, and finally kept the PW4 and the Forma, the ability to easily customize the Forma really stands out in its favor compared to Kindle. Not only can you patch the firmware, but also you can enable dev mode, and access the Kobo's .config files, 2 other quick ways that even non-technical users can use to modify the hardware or software behavior.
