[Paperbackstash]

Default - I like Bookerly as a default Amazon font well enough since it's well-rounded and easy for the eyes to absorb, but it's not my favorite. Personally I can't stand the Amazon Ember font. With the default fonts of the Paperwhite, I would choose between Bookerly and Palatino - which is a nice balance between rounded fonts and narrow letters and a good amount of spacing. Baskerville is a beautiful font but I don't like it as much for hours of reading on e-ink. Tested all with 4 size and bold 1.

For custom fonts, ChareInk is nice for the weighted with the bold turned off. Installed the Non-weighted but for some reason it's not loading, will have to mess with that later. Constantia is pretty but too light and small for me. DejaVy Serif E-Ink is nice but didn't suit me as well as I'd hoped from the reviews. Noto Serif is a top favorite for easy custom and rounded.

It surprised me but my favorite so far is the Linux Biolinum. I'm usually not into narrower fonts but this one with a bold 1 setting is an immediate ease on my eyes and I swear increases my reading speed a bit. Turning it up to 5 size over 4 helps even further, while that's too much screen real estate for the other fonts. My favorite setting with this one is Bold 2, Font Size 5. It's a very basic font but seems well suited for me.

Now if I could just figured out which brightness I prefer on the Paperwhite...
