> I consider PDF viewers to be superior to the experience offered by ebook viewers. For example, Having to tap the left and right side of the screen to move between pages is a pain compared to swiping up or down in a fluid motion.

> […] On the same device PDF viewer will zoom text to use the entire screen with a double tap of a paragraph.

I believe there are shortcomings of the ebook viewing software, not the ebook format.
