I'm a somewhat experienced CV player reaching Essex and Hiryu, and I must say that I'm not impressed with Saipan. Not being able to have both TB and DB is quite unsatisfying, and the 2/2/0 load out put as many planes in the air as the old Langley or stock Bogue. Having experience with both IJN and USN CVs, I must say that more planes packed into fewer squadrons feels much better.
9 bombers in one squadron seemed quite tempting, but 10000 damage per drop sounded quite unsatisfying, as I can achieve the same with each one squadron of 7 planes on the Essex, and she had 3 of them in addition to a TB squadron. Handling many small fighter squadrons doesn't feel good either.
The problem I'm having with Hiryu is that she has only T6 TBs and they are torn part by T7 AA. I guess this won't be a problem for Saipan, whose TB will supposedly have >2k hp. The problem I had with Ranger was that I kept using the 1/1/1 load out and I wasn't experienced enough to avoid enemy fighers. I believe I'll do much better on it with 0/1/3 load out now, seeing how I play the Essex with 1/1/3 just fine without making too much use of the fighter squadron. I don't believe Saipan can be as good as Ranger and Hiryu.
