Tribbie vs Anaxa for Erudition-less account.

I have a guarantee and want to get either Tribbie or Anaxa at E0S0, then save for Phainon. I have no limited Erudition and no interest in one except Anaxa, so no the Herta to pair with Tribbie.

DPS I use: Boothill, Blade, Aglaea, Imbitor Lunae, Himeko, Clara.

For Harmony I use Sparkle, Sunday, Bronya and Ruan Mei. No interest in Robin, so I thought maybe Tribbie could work as a second team buffer bc Ruan Me is tied to break team.

Would Tribbie or Anaxa be a better choice for my account?
