Simple examples of differences that even an end user can appreciate:

In MOBI it's impossible to have text and images side by side.

In MOBI you cannot embed fonts which means it is completely unsuitable for mathematical/foreign language publications

In MOBI you cannot format poetry

In MOBI you cannot have multi-level Tables of Contents

In MOBI you cannot have images that look the same at all resolutions (scalable/vector images)

In MOBI it is impossible to have semantic content, which means for example that you cannot re-use the insert book jacket feature in calibre to convert metadata into a book jacket.

And that is just the tip of the iceberg.
