Are you high Tirpirtz?

AD is much fun and with far better spread and great AA slot.
Bizzy is fat, slow, broken spread, poor AA slot.

Range: Bismarck
Supports: AD
Guns: Bismarck

I perfer the Andrea Doria because it is tiny, has a amazing turn rate, and pretty good
speed. It also has 2 more shells per slavo than the bismarck. You can get out of almost
any tight spot. I loved that ship. Bismarck is a lot fatter and a bigger target for other
BBs because you are bigger.

Short answer use both

Bismark is the better ship, it is faster and has better range (you can start to play with
some of the big boys)

AD has better support slots, hits hard, turns fast, and has a tiny hitbox.

but heres the catch Bismark to level your bo and AD to level your supports (throw a
support in the BO slot instead of your BO

run one for a couple of days then switch, it will keep your supports closer to level of your
BO and you get to have fun with both ships, way different play styles but both are fun
