After trying out all of the major readers and a number of the minor ones, Librera is what I've been looking for for years. It handles large epubs well, is fast, has a ton of customization options, text-to-speech, built-in Drive/Dropbox/Onecloud/OPDS downloads, and a good UI that makes sense and can be navigated quickly. As opposed to most other readers I've tried, it's a genuine pleasure to use.

LOVE IT BUT ITS GIVING NE A BUG. It used to give me a notification like option that let me move forward a page when listening to things being read, but it is no longer popping up. Also it would be nice to have the option to skip half a page instead of having to make the words large to do so. It occasionally will not move forward a page when it is reading out documents or epubs. This is my absolute favorite app and I used it to listen to a story for three hours at work and outside of it.

I've been using Librera Pro for years, but a couple of weeks ago it was updated on one of my Samsung tablets and no longer works. It's an older model, running Android 10, but it still does everything I need. Its primary use is reading. Now it won't read books, it only displays a blank screen. I sent an email to their support address, and have not received any response. In my opinion that's unacceptable when a program update makes the app unusable.
