I found that only small part of technical PDFs can’t be read comfortably on Kobo forma with Koreader. Some of them have coloured graphics, some of them are true A4, others are just huge and kind of “pictures” not recognized texts. For that even 10” tablet is not good enough, I read them on iPad 12.9”. But for 85% of books Forma is quite adequate.

I also have an old Kindle DXG with koreader and can compare them directly: on Forma everything looks better, because resolution is much better and reader works much faster. For me it has only one drawback - no handwritten notes, only highlighting.
