I haven't heard players voice concerns on these ships, and folks that are annoyed about something can and will be rather vocal. Is there something about these ships that brings them to the front of your mind?
I can't speak to all of the ships you brought up, but:
Ognevoi's shoudln't be a Torp Boat. Not like "Torpedo Focused Destroyers" per se. The guns on the Russian DD line are wonderful to use and the Ognevoi is the first of the split where both Smoke and Heal options are provided.
To my knowledge, I'd only heard good things about her?
Hipper has features that do stand out compared to the Tallinn
203mms with extreme HE Pen (51mm Pen)
Faster Reload than Tallinn (though less guns)
Torpedoes
Standard German BBs continue to be effective. They are armored in ways the Schlieffen line are not which is very important in terms of longevity. It's normal in games to accept less Damage when you have more Health/Armor, and the two lines reflect that.
The only things I've ever heard about the Montecuccoli was that he guns felt weird. The 203's are introduced at Tier 6, so her shell flight/interaction supposedly feels different than others in the line.
Uniqueness is not a bad thing as it helps to provide different play experiences across the hundreds of different ships we have in our game.

If you wanted to get more deep into a discussion on thos ships or others, I'd drop a ping for @Boggzyto have a look at your thoughts.
