I've playd both and I really can't complain about either of the two, there both
wodnerful ships, just a word of advice though, at lower lvls make sure you rotate
your sailors in and out to keep there levels close together due to me being at say lvl
120 and my pilots scatterd by 15 level differences...=]

Level gunners on cv for bb6

Trust me having level 120 gunners for nagato all the way to super yammy is hella fun

Well I have a De Grasse and a Yamato, I got my CV6 first for a couple reasons, first I
just kinda enjoy playing CV, and IJN has quite a few CVs and Remods to choose from, making
the grind slightly less boring.

Second, both the BB6 and CV6 are very expensive, so unless you have some good sailors
you're willing to sell (I don't roll and grind sailors just to sell them), you're gonna
need to spend alot of time in a CV to earn the credits/points required.

Third, CV6 requires 12 sailors, BB6 needs 14. I simply didn't have enough to get a BB6,
so I figured I'd level the De Grasse first, and then I'd have a couple spare 115+ pilots
to use for the Amagi.

The downside to CV6 is that in GBs, you often have the best BBs stacked against you. I'm
sure they stack against BB6 as well, but at least a BB6 can defend itself.

That being said, I found that grinding an IJN CV seemed to go much quicker and easier
