If I'm reading https://picard-docs.musicbrainz.org/en/a...pping.html correctly, they're the same thing: "performer" is Picard's internal name, but it saves the values to the ID3v2.4 frame TMCL, which mp3tag and exiftool display as MUSICIANCREDITS. And "arranger" (etc.) are saved to TIPL, which displays as INVOLVEDPEOPLE.
