FBreader is my daily driver, I tested all of them and some are slow, others have pagination issues like Neoreader where the pagination is wrong, you read the first page number 1 and you move two pages ahead and it still shows page 1 (is an example), in FBreader the pagination counter advance as you move ahead in the pages like a normal book, the same issue of bad pagination has AIReaderX. The one I could like is Moon Reader but there is % of pages (no numbering), I wonder if the developers have ever read a book that shows only percentage instead of page numbers
