It should be lightweight, be able to read local files, respect book css and have an intuitive design, and be regularly developed.

Before you respond, note that these are the ones I have tried:
Play Books, Kindle: My preferred choices, but they both require uploading/sending ePub files and then downloading them again.
Kobo Books: Not lightweight at all. Very slow.
Readera, Moon+ Reader, eBoox, eReader Prestigio, Librera, FBReader: Do not respect book/publisher css.
Lithium: Does all the above but isn't developed. Also slow.
Aldiko (now Cantook): Does all the above but a bug (long lines like urls do not get cut off at the end of the screen so they go into the next page and cover the text on it; see attachment) that I have reported since 2 years has not been fixed. Also, can't zoom in on images.
KOReader: weird and not intuitive design, also, didn't seem to correctly detect the screen size of my device, as text went off screen
Pocketbook seems to be decent but it needs a lot of customization to be good. I'd like something that works right off.
Something like an Android equivalent to Apple Books. Or, Play Books but it doesn't require upload.
