Calibre is an ebook library manager with a reader built-in. Koreader is purely reader software, and it works particularly well on touch and eink screens.
That’s why I referred to it as “plain”: it’s just the reader. And it is mostly made to replace the original reader software on eBook devices, but you can also use it on desktop if you want.
The question is if you are looking for just a reader, or a library manager. But you can also mix the two, so use calibre fo manage the library and have it use koreader to open books
