For a while, HydrongenAudio, arguably the best sound/music related forum, did plenty of listening tests.
The last one sadly is from 2014: they tested Opus, AAC and Ogg Vorbis at 96 kbps against a classic MP3 128 kbps, and find out which codec produces the best sound quality.

Notice that it is almost 10 years old, and that MP3 was encoded at 128kbps.
