But personally, I third the vote for Vittorio Veneto.
She had quite the operational history... And the class will be glorious fun.
Good armor, good speed, beautiful lines, decent AA, and the most powerful 15in battery ever mounted, 3x3 15in guns in turrets that turn fast enough to make some cruisers jealous... And incredible range on this guns. They'll be quite accurate too, since WG doesn't take into account shell qualtiy.
Something has to be balanced against those guns being great in every other respect, so it seems like wider dispersion would be the obvious choice.
