KOReader is so good for reading PDFs, compared to the native reader, I’m very impressed. Supports proper landscape mode (where swiping to next page moves to the second half of the current page, THEN next swipe gets you to the first half of the next page), supports auto-rotation, support auto-cropping of PDFs with controllable margin (killer feature), supports contrast adjustments, … It does not support handwritten annotations, but for just reading PDFs - it’s perfect.
