I am thinking of switching from my paperwhite to a clara HD
I have a bunch of epubs in calibre
Standard ebooks say that for kobo one should use their kepub files rather than epub files because "[although] Kobos can open and read regular epub files like the compatible epubs we offer for download..... doing so triggers Kobo’s bad ebook renderer, which is based on A.D.E"
https://standardebooks.org/help/how-...books#kobo-faq
However, in calibre you can set it up so that epubs in calibre convert to kepub on sending to the Kobo reader.
So my question is whether there is much material difference between
a) sending a (well formatted) epub file to the Kobo via Calibre which converts to kepub)
b) reimporting the books as kepubs from standard books and then sending them to the Kobo (via calibre)
