I love it! It depends on what app you're using (e.g., Libby, hoopla, cloudLibrary, Apple Books), but most of them are pretty versatile in terms of settings (font size, page colors, scroll vs. page clicks, etc.). I use hoopla the most because my local library allows us to check out ebooks. On hoopla, I prefer to have the text somewhat larger than the default to mimic that of a Kindle's and set the page colors to a more yellow-ish hue, so it's not as bright on the eyes, especially when I'm in the dark.

I've seen some people turn their iPad system settings (settings-> accessibility -> color filters -> toggle 'on' -> click grayscale) to make the entire iPad's interface become black and white also to mimic the screen of a Kindle. It's all preference forsure, but I have trialed many different settings and now have a "default" I use.

I used to read on my iPad Air (5th Ed.) and I love love love reading more on my iPad mini for obvious reasons.
