In my opinion, the bismarck is the best BB3 that I have played. And I have played all US, UK, and KM BB3s.
range (of course)
spread (compare to other bb3s)
gun angle (30)
gun firing arcs (can point all guns almost totally forward / backward)
size (compare to OP 2 and Hood)
damgae (lowest in tier, I think)
speed (37/38, not fast, but manageable)
AA ability (only 3 slots each side)
I highly doubt you only have 1 BO reset from event, so you can try to and if don't like change back.
