Not all of them. Dwarves can grant themselves Tremorsense multiple times a day. That's really good! Humans keep the extra 1st level feat and also get inspiration for free every day.
(Variant) Humans do not keep "the extra first level feat". Humans used to have access to some of the most powerful feats in the game (e.g. Polearm Master, Great Weapon Fighter, or War Caster). They now get the extra inspiration to make up for the fact that they are restricted to the sort of feats like Skilled or Tough that no one ever took. The weakest variant humans are significantly more powerful but the strongest are actively slightly weaker.
Rogues are quite a bit stronger, even before you factor in weapon masteries. So are rangers. So are monks. If you don't think classes as a whole are stronger, I don't know what to tell you.
If you think that either rogues or monks were strong classes rather than among the weakest classes in the game I don't know what to tell you. And rangers aren't a lot stronger than
Tasha's rangers, while the
PHB ranger was so bad they had multiple revisions.
Paladin is the most powerful class in the game, so if they're a little weaker, good.
Debatable that it is more powerful than full casters - but yes, that's the point. The rogue, ranger, and monk can now hang with the paladin. And the sorcerer should be able to hang with the wizard.
The goal is that a party of wizard, moon druid, cleric, and paladin should be more or less unchanged in power from their classes (probably slightly nerfed) - while a party of four elements monk, sorcerer, assassin rogue, and beastmaster ranger, all without Tasha's, will be
massively boosted to the point they can hang with the wizard, moon druid, cleric, paladin party.
