I love your take on this, I also have all 3. Playing Neustrashimy in ranked was one of the most enjoyable ranked seasons I had, and I wish there were more competitive places to play it. Black is fun, but if you aren't fighting DDs it's mostly area denial and capping. Somers is a very fun boat and torps are great, especially after you speed them up with the captain skill. Overall, I like Neustrashimy the most. As you said, easily the most versatile of the group, the repair party is ridiculous, and most players think it's guns are awful but are in for a huge surprise.
