Have you read the Wiki item?

I prefer EPUB which has good CSS support and works natively on many portable devices.
HTML on a Computer allows more control and interactions than EPUB, but does not always translate to a device .
Almost all conversion (not just e-books) introduces Loss, Noise (strange artifacts

) Avoid conversion if possible. Editing is preferred to conversion as the edit (usually) only makes
those changes.
