I mean I dislike PDFs for the exact reasons you cite, they don't reflow and fonts are embedded and chosen by the creator. Occasionally these choices can be good, but often I want to resize the text-size to make reading more comfortable which is easy with HTML or an EPUB, but with PDF I can only zoom so much before I must pan to actually read the entire line. Similarly, I think that the creator's font choice is often the wrong choice, it's very common for me to change fonts on an EPUB, but I can't do that for a PDF which is frustrating.
