Which is better OPUS or m4a?
Since this sample has AAC with a bitrate higher than OPUS, it would be better to go with AAC, since bitrate is the limiter for the quality of your audio. 128kbps of mp3 would be better than 64kbps of m4a, even if m4a is more advanced, because m4a would cap off at 64, while mp3 would cap at 128.
