I absolutely dislike the pdf viewer in Chrome. It fails at even the basic things a pdf reader should support. E.g., it lacks a concept of pages. You can't jump to a certain page. You can't even know the total number of pages. It doesn't support the pdf's TOC. For any pdf which contains more than one page it is therefore useless. I can't understand how the Google folks ever thought this was a good idea.
I prefer Okular or Evince for Desktop viewing and pdf.js for in browser viewing. pdf.js is a bit slow when loading the pdf. But the user interface is quite nice in my opinion.
On the other hand its one of the (or the? at least last I checked) only pdf readers on Linux which supports subpixel rendering of text and other vector content, which makes documents much more easily readable in my opinion.
