Overall, I don't think I would count additional uses, just new uses.Which do you regard as a feature: the ability to do something new, or when you get to use an ability an additional time?
From here, it looks like the former. So when you pick a Fighting Style or a 1st level spell counts, but you don't count when you get an additional action surge or your 3rd 5th level spell slot for example?
This is why I said you could count Spell Mastery as possibly two (two different at-will spells) and Signature Spell as two, so the range was 15-17 because of this.
So, I am not counting additional uses of Action Surge or Indomitable, nor more spell slots since Spellcasting really is the feature.
I suppose technically you could also count proficiencies as features as well:
Fighter: +10 (three armors, shields, simple weapons, martial weapons, two saves, two skills) vs.
Wizard: +5 (some weapons, two saves, two skills).
Which, if you count access to each new spell level as a separate feature, would bring the totals to:
Fighter: 29
Wizard 28-30
Pretty darn even by that reckoning anyway...
