He / Him
I have seen new players at my table rely a lot more on their Background / Ideal / Bond / Flaw for character motivation and traits than their alignment.
As a DM, I would much prefer a codified set of Motivations or Behaviors for monsters than alignment. If a Bandit had the traits Greedy, Cowardly, that tells me a lot more at a glance than Neutral Evil. Especially if the Monster Manual or DMG then provided some guidance on how enemies with those traits acted. Something like "A Greedy enemy will first target characters with expensive items, attempting to knock them out and steal their weapons or rings. A Cowardly enemy will often attempt to flee once it has lost half its hit points."
