The Market's Favorite Boosters

I look at CZ and see a lot of needs filled;
    Out side of a few; most of the so called glorious units are done and that 20% to 25% remakes per set does limit one;
But i still think the set did the game justice
    Canada;; gets is first none DD
France;; its First Planes, CV and new class of BB
    How much do we love Mare Nostrum so Greece is added
with a very useful DD a UK G-H Class how many nation had one of those.
    UK;; First PB with Loiter and a new class of BB; lowest cost for a 8-14-5 BB
USN;; First HI Level Bomber; EE is introduced; First rocket attack fighter;; new class CA; and How versatile is WEE VEE new class BB which can be used post and pre PH
    with Tenn and Cal models
Russia; First real BB
    Germany; Not pretty but how about a TB for its CV;; New class CL and DD along with instead of going fantasy he finishes the last of the real German BB's
Italy; New class BB with First Flag;; First all three capable attack PB;; A Sub par with the Germans
    IJN;; First cap 2 CVL;; First none Zero Fighter;;New Class of CA; First low cost DD and how good is Chikuma

 How good would this set be with just 3 changes; say      Kaga for Junyo
                                                                                Nelson for Arkhangelsk
                                                                                Atlantis for Vainamonen
