Monte Carlo vs Ataccama ONE
Four of fourteen models named Monte Carlo first on the direct prompt; zero named Ataccama ONE. Monte Carlo was named by fourteen of the fourteen models and Ataccama ONE by eleven and Monte Carlo carries 51 labels and Ataccama ONE 15, so the shares are not directly comparable.
Named in four categories this edition.
Named in three categories this edition.
