Opro

Dland >> Hipper
PPro > >> Prinz
PPro2 = Scharn
Opro > Gneis
Opro2 > Bismark

Its somewhat a personal preference thing but overall Opro line is far superior.

-Dland has better range and spread then Hipper.
-PPro is an amazing CA and the best pure AA platform.
-I liked PPro2 better then Scharn myself though they arnt much different.
-Opro1 is faster and skinnier then Gneisenau and has better AA firing arcs.
-Opro 2 is faster then Bismark with abit more firepower. It also gets an extra crew slot.
-Bismark does have a better spread and slightly better range but I do not think that
outweights O2's advantages.
