Same here. It helps to have a solid PDF viewer (I use Okular), but what's also really underappreciated is the vastly better typography in PDFs. I suppose it depends partly on the viewer, but epubs tend to be hot garbage to look at. Fortunately ebook-convert (from the Calibre project) generates great looking PDFs and lets you set a bunch of options like fonts and so on. This is especially important if I'm on mobile, because I can create an easily readable PDF in portrait mode that works great with the Android default PDF reader, whereas the obvious choice to open epubs (Google Books) is terrible: it's slow and battery heavy, and requires you to upload the epub so that it can be converted into the native format. (Once the conversion process choked and I somehow ended up with a 1 GB file.)
