Coming from the Kindle Voyage, which was my first ever e-reader, and planning to upgrade as a birthday gift to myself. Been reading a lot about the Kobo Libra 2 and I feel like the ergonomic design and the expansive file support make it a better option for me, but I'm concerned by comments I've seen on here about the Paperwhite's performance and battery life being better. Can anyone here who's used both tell me more about their experience, especially if you disagree about Kindle PPW > Kobo Libra 2?

Also, an aside - are there any other e-readers worth considering, or are those the best two options on the market right now at that price point?
