Barbarian, Bard, Druid, Paladin, Rogue, Warlock, and Wizard -- all have a suite of subclasses I can get behind, even if it's not my preference (Celestial Warlock and Abjurer Wizard feel under-reasoned to me.
Cleric -- good. I love that Trickery was included (and imporved along the way). I would lose War, since heavy armour is coming with a level 1 choice.
Fighter -- brawler is fine, but it's better as a fighting style (as in Tasha's) not a subclass.
Monk -- I don't have a clear sense yet.
Ranger -- gloom stalker always rubs me the wrong way.
Sorcerer -- aberrant and clockwork are disappointments. Divine, Shadow, and Storm (=the Xanathar's options) are all more iconic.
