Not really. Sure, they are good (stat-wise) but the difficulty in getting them is a bit higher than all the other CVs (Blueprint + Flight Deck, which some don't have). I'd say if you have most of the CV except Taihou even if they're not Kai ni then you're good (although getting Hiryuu and Souryuu Kai ni is good)
