It is ranked #1 by Book Industry Study Group (BISG) in their EPUB 3 support grid:

Major publishers such as Pearson, McGraw-Hill, and SAGE have certified our Reader. All of this is working within a standard browser, making it easy to integrate our Reader in other sites or third-party apps, while fully retaining all its functionalities, such as note-taking, highlighting, bookmarking, full-text & metadata searching.

A JavaScript API can be used to control the Reader and receive various events. The API interface itself is a small, compact JavaScript layer, that can be loaded from any domain, and which communicates with the Reader through cross-document messages.

On top of the browser solution, mobile apps for Android, iOS devices (iPad or iPhone) are also available.
