I have no experience with the Kobo, but for Kindle Keyboards (not sure about PW/Touch) the OSNOVA versions are about the best.
Here is the WEB Bible published by him:

His versions tend to have decent navigation at least on the K3/Kindle Keyboard. The version I have (NET Bible) has a table of contents with chapters too, although I rarely use it, the "direct verse jump" feature is much faster for navigating. See this thread for more information:
