I still use it with SD-2s to level most of my sailors to 60, the range, ROF and damage of the SD-2s suits me just perfectly, but you do need good reload gunners for them really, mine are lvl 105 now, I cant remember when I was last used to them being slow.
I have also used a moltke, which obviously provides a combination of excellent ROF and damage with relatively good range, but those guns are better compared to the Minizinis, which do slightly more damage with about the same range but twice as slow.
Its an excellent AA ship, SN AA is very good, SD-2s for range, Minizini for short fast fire.
Its much better than the svetlana, more dp, more total T slots at better angles, actually able to USE the SD-2s. The PCAs are all pretty much designed to be very good AA boats, it even says that in their item store descriptions. Obviously they arent all very good, but the Petropavlovsk, Motlke and Asama are all very good AA ships.
How it compares to the motlke is based on which guns you use imo. If you use the stronger, slower, long range AA I prefer the Petro, if you want the short range, fast firing AA, the moltke is better.
