Brennus as the least-bad Fleet of Experiments battleship

Which ship in the French Fleet of Experiments was the most capable?

Brennus, judged only against the other compromised designs in the group; the choice carries no endorsement of it as a satisfactory battleship.

Brennus is the reluctant choice among the French Fleet of Experiments because it tended to function more often as an effective combat ship. The comparison is limited to a deeply compromised group of designs. Even its most capable member receives a poor assessment.
