I don't play a lot of Bards and I am playing a Glamour Bard for the first time and man this subclass is really top notch. I would put it up against any other subclass in the game. As far as a subclass goes, I think it beats even Twilight Cleric and Gloomstalker, two of the most common subclasses labeled as "op".
All of the subclass abilities are extremely powerful and have been what I would call "S tier" in play
Mantle of Inspiration giving 5 players free movement off turn without AOOs and getting temp hps to boot and being able to do this up to 5 times per short rest.
Enthralling performance is an incredible out of combat/social ability.
Mantle of Majesty - Command every single turn as a bonus action for one combat a day.
Unbreakable Majesty - Pretty much a Sanctuary for an entire battle that is not broken by attacking or casting spells, with the added benefit that it is a Charisma save and if the enemy does save and get to attack you he also gets disadvantage on saves against your spells the next turn, and it recharges on a short rest.
