I still store most of my music in iTunes (renamed to Music in later macOS versions). I’m also happy with the tag editing of iTunes, especially after installing some custom tag-editing AppleScripts from https://dougscripts.com/itunes/index.php and modifying some of those scripts.
However, I am rethinking storing all my music in iTunes given that it can’t play Opus or FLAC files (last I checked) and it makes loud glitchy sounds when it plays an MP3 file whose sample rate is 32k instead of 44.1k. I’ve already had to give up on storing all my music files in the iTunes folder now that my entire music library doesn’t fit on my laptop’s storage. Thus, I have been using Meta more.
Edit: I see another commenter also mentioned Meta and Music.app: https://news.ycombinator.com/item?id=40471849
