There isn't one, although depending on the device, some reflowable formats may look better than epubs. (LRF comes to mind. And my Clie doesn't read ePub, so eReader is a better format for it.)
However, non-reflowable formats *designed for user requirements* are currently better than ePub in some cases. A PDF that's designed for the screen size it's being read on, and set to the preferences of the reader (with/without margins, extra lines between paragraphs, indents, justification, etc.) is easier to read than ePub.
And while ePub is great for reading novels for entertainment, it's got some serious problems for academic use--lack of good page indicators makes it hard to use for reference work.
The fact that nothing reflowable is currently better than ePub doesn't mean ePub is perfect.
