Definitely a big NO to both of your questions.
Pesently there is no E-Ink device that is "good" for PDF files because they are to small (PDF being mostly A4). E-readers are purpose-built for ebook files like EPUB, MOBI, RTF..., PDF not belonging to this list.
622 has a better reading app for PDF than most of it's competitors but it is still cumbersome, 912 is a little better because of it's 9" display. But if you read solely PDFs you are better off with any 10" tablet.
