Odette is above average I would say. Victoria and Seren are flat-out superior to the rest, Ho-Rii is OK but her skill initial is off-putting, T-100 is good but if you're not careful her range reduction debuff can end up letting enemy tanks slip past your blockers, Sturmtiger needs too much emblem help to be viable for her cost, Tortoise is meh for her cost and the new event destroyer is also meh for her cost.

IMO for Destroyers:
Seren > Victoria >>> Odette/Ho-Rii/T-100 >>> Sturm > Tortoise > GMC
