eInk eBook reader for reading scientific PDF papers (as of 2018) While reading lot's of papers for my Thesis, I was looking for another solution than printing important papers. So I started browsing the internets, watched tons of reviews on YouTube, etc. 

I learned that, as of 2018, most of the current eInk eBook readers support PDF reading. However, none of the reviews covered, if the readers can be used for highlighting and adding annotations to the PDF-files as necessary for a sufficient literature review. 

Therefore, I wanted to ask if any of you can share their experiences with certain devices and include some advantages and drawbacks. Some rather outdated discussions on this topic does not cover current devices. 

I thought that probably devices that support working with a stylus (such as Onyx Boox Max, reMarkable, etc.) are more suited for excessive reading (and marking). What do you think. 

I'm not asking whether or not to read on an eReader, but trying to shed some light on which device in this giant ecosystem is suitable for the needs within academic work.
I love my Kindle and was looking for a solution that would allow me to read scientific papers on epaper display. Generally, that boils down to finding a reader that has a screen big enough so that it can acomodate single PDF page, with margins possibly removed. 

I don't annotate printed papers much, so option of having a stylus is not deciding for me. You'd have to think how much marking does your workflow involve. For me, the speed and software quality of a reader are first priority for me, as you have to be able to read comfortably before you can start thinking about annotation.The screen has to be also big enough to read PDFs comfortably.

That said, recently I have been contemplating two readers: reMarkable and soon-to-be released Onyx Boox Note, both sporting a little more than 10" display. Both adverise as supporting marking of documents. The reviews for the former unfortunately point out that it's reading experience is sub-par, the latter has not yet been reviewed, as far as I know. I've also emailed manufacturers of those solutions and asked for a precise dimensions of active part of the screen (to know whether PDFs fit well). Nobody answered, what is not very reassuring.
EDIT: reMarkable manufacturer has replied stating that the screen dimensions are 210x162 mm.
