Part of what makes it so good is that it's everywhere. Preview, QuickLook, QuickTime Player (yes, videos get OCR'd too!), any app that uses the system frameworks for displaying media.

This includes Safari, where not only do images (inline or otherwise) have selectable text, but the built in translator leverages that text and uses it to translate images, too! This is super useful for translating Japanese webpages in particular, which tend to have tons of text baked into images.
