I bought that 21 crate deal

I'm so glad I bought that deal, I managed to get 6 ships and 2 commandes!

Ships:

Elephant, Pbag B, Alaska B, Black B, Independence, Marlborough

Commanders:

Robin le fierce Andrew the lip

I have a few questions about the things that I got as I am not the most experienced player.

Are the 2 commanders I got good? I currently have Nikolay for my ussr cruisers, but if Andrew the lip is better should I level him instead? What about Robin fierce?

Then is the Alaska B good? I know it's a legendary and I'm worried taking my level 11 sims in lol. I'm aware that pbag is good and I killed it with the elephant. Black b was eh but I've never been the best with DDs. Independence is the same as black B. Marlborough seems pretty bad, tbf though I have a level one commander so I know that's not helping any.

Any tips, tricks, or info you guys have would be very much appreciated!!
