* SugarWiki/AwesomeMusic: Their first eight albums qualify from start to finish. Some people also throw in ''The Missing Piece'', ''Giant for a Day!'', and ''Civilian''. As for live material, ''Playing the Fool'' is among the greatest prog live albums ever made.
* BrokenBase: The Gentle Giant fanbase is torn as to which of their eleven albums is considered their best. Popular choices include ''Acquiring the Taste'', ''Octopus'', ''In a Glass House'', ''The Power and the Glory'', ''Free Hand'', and occasionally ''Interview''.
** The quality of the band's last three albums. Some say that the new-wave influenced direction was the band selling out and putting fame over music, while others say the albums are quite good and reveal a unique side of the band that was never fully explored.
** ''Interview''. For some, it's the last great Gentle Giant record before their last three pop albums, while for others it's a mess of underdeveloped, derivative songs tied around a silly concept that showed the band struggling to rush an album out to sustain the momentum ''Free Hand'' had given them.
* EarWorm: For a complex song, "Talybont" can be seen as this.
** Hell, even "Knots", "Wreck" or "Proclamation" are very catchy, really. Accomplished via slightly unusual tunes. It could be argued that Gentle Giant's one of the more catchy prog bands.
* EpicRiff: [[https://www.youtube.com/watch?v=uu6fmx-xn9A This]] certainly qualifies.
** "[[https://www.youtube.com/watch?v=BTet3C_afKA The Boys in the Band]]" is a pretty good example too.
* [[GermansLoveDavidHasselhoff Italians Love Gentle Giant]]: They were most popular in Italy. This was the case with many prog bands; somehow Italy really took into the genre.
* NightmareFuel: The vocal bridge of "Pantagruel's Nativity".
** Also the spooky "Alucard".
* SuspiciouslySimilarSong: The title track off of ''Interview'' is often accused of sounding similar to "Proclamation" from ''The Power and the Glory''. Both tracks have a similar keyboard jig feel to them, with similar tempos and vocals.
* TearJerker: "The Moon Is Down", "Think of Me with Kindness", "His Last Voyage"
