I have been doing this for a long time, and FreeDB's metadata is way, way worse than MusicBrainz's, and has less coverage too. If you find any issues in MusicBrainz metadata you can submit a correction, which will be reviewed and voted on by community members. I've done this maybe 4-5 times for my collection of about 2000 releases and in each case, my correction was quickly accepted.
