what is the best ship?

There's alot of options

Alot but what is the best one?

what the best one tho

There is no 'best ship'.
Each nation during WWII took different approaches.
Some were strong, some had big guns, some wanted speed.

For example, the Atlanta is a lightweight cruiser. VERY fast fire rate. Rains down fire like nothing else. But has very little armor and a citadel that is easy to reach (weak structure). So you can lob shots out, just dont be a target :)

Then you have some battleships that are extremely strong. Guns aren't great, but you can drive straight into the heart of a battle, take a beating, disrupt the other side's plans, and still come out alive. Bruiser ships.

And if you want to have some crazy fun, some of the single fire Tier 1 ships are great. Our clan would just go play those, took skills to have a single torp or slow shooting guns (post WWI)
