Unlike emissive display technologies, E-ink maintains contrast in well lit environments. On a sunny day, my Kindles and ReMarkable are a joy to use outside, while my Pixel needs it's OLED cranked up all the way to be visible. In low light environments things reverse. OLED emits light per pixel and cannot be beat, while E-ink backlights are kinda fuzzy (reminds me of the old LCD clock/watch backlights). That being said, for reading static text it's perfectly adequate, and I tend to prefer the distraction-free nature of the Kindle.
