* 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 considered the last great Gentle Giant record before their last three pop albums, while for others it's a mess of underdeveloped and 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.
* LoveItOrHateIt: Gentle Giant, like many progressive rock bands, has their share of supporters and detractors. Supporters hail them as being one of the genre's most underrated bands with complex musicianship that blows even the genre's major figures like Yes and Genesis out of the water. Others contend that they suffer from the same excess and pretentiousness as those same bands, if not more so, with certain aspects of their music (dissonance, odd vocal harmonies, Derek Shulman's singing, etc.) being either loved or criticized.
* NightmareFuel: The vocal bridge of "Pantagruel's Nativity".
* 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"
