ePub (RMSDK) on Kobo used to be slower. But that's been sped up so it's not too slow. Dithering is not much worse with ePub. As to the speed of displaying images, I've not compared them. But given how ePub is not slow to display the cover and title page, I'd say it's not too slow to display images.
Kepub also has better support for Epub3 features,, including the Epub3 standard for ToC.. (which the epub renderer ignores,, making it unable to handle epub3 files unless those files are generated with backwards epub2 support.)[/quote]
Yes, KePub has better support for ePub 3 features. But why make an ePub 3 without an NCX unless it's heavily reliant on ePub 3 that it won't work well enough with an ePub 2 only renderer.
