Well, picked up the Saipan and I must say, she's definitely meant for experienced and skilled CV captains. I'm only a casual CV captain.
Do I regret getting her? No. Can I use her effectively? Nope. She's tricky, since her 2F/2TB load out only has 3 planes per squad. Screw up with the TB's and you'll lose them all before they get their torpedoes off. With her 3F/1DB load out, still only has 3 fighters per, but 8 dive bombers. Since they use 1k bombs, they can do CONSIDERABLE damage, if Mistress RNG decides to grace you accordingly.
I won't venture out of Co-Op with her in the foreseeable future.
