I no longer have a Kindle to compare, but I'm very happy with build and lighting on my Kobo Libra 2. I've used Kindles since the Kindle 1, and there are some Kobo things that I don't like as well as Kindle, but it's a better-than-decent e-reader and I'm glad to be out from under Amazon's thumb.

I've been happy with the half dozen Kobos in my house.

Weirdly, about half of them have developed a problem after about 5-7 years, whereby they intermittently stop charging. Replacing the battery doesn't seem to fix it. Might be a problem with the soldering of the USB connector to the PCB?

As a bonus they are Linux based, and you can do fun things like replace internal SD cards with bigger ones, login using telnet and install new applications.
