FLAC: Values written to Vorbis comment.

APE: Values written to APEv2 tags.

Track Gain: increases or decreases the volume of that track to on average 89 dB. All tracks will be at about the same loudness.
Album Gain: increases or decreases the volume of the album to be on average 89 dB. This allows quiet tracks on the album to remain quieter than the loud tracks on the album.

Basically if you listen to an entire album at a time, you should use 'Album Gain'. If you listen to shuffled/random tracks, you should use 'Track Gain'.
