Ogg vs Opus
Ogg is a container; Opus is an audio codec. They serve different roles rather than competing as equivalent formats. An Opus stream may be stored in Ogg or handled with an .opus file, depending on the workflow.
Which format should you choose?
When using Opus, verify the container or file convention and confirm the target player supports that combination.
