EPUB
Convert to EPUB when you need a flexible, reflowable ebook for wide distribution, library use, independent publishing, or archival storage of structured long-form text.
It is the right target for novels, manuals, educational content, and narrative works intended for multiple reading apps and devices.
Choose EPUB when portability and reader adaptability matter more than exact fixed-page layout.

3G2
Convert to 3G2 when preserving compatibility with legacy CDMA handset recordings, telecom media archives, or workflows that explicitly expect 3GPP2-style mobile video.
It is useful for migration and recovery of old phone clips.
For current playback and sharing, MP4 is almost always the better destination.
