@pepak,
You have asked a straightforward question which unfortunately has a less-than-straightforward "best" answer.
Having spent a very long time sorting out this problem for myself when I moved from Sony to Kobo, many years ago, I can probably offer some suggestions. However, in the interest of not wasting time (you reading, me writing
) answers to these questions would help.
- will you be using calibre to transfer your books?
- do you intend to read your books as standard epub or will you be using calibre (or Kepubify) to transfer them as kepub format? Font handling in the kepub renderer is different from the standard epub Adobe renderer.
- Have you given any thought to whether you may decide to use the kobopatch system to apply many and varied optional tweaks to the firmware.
