wrt the choice between Daves, I had lunch with a grown up RAF 2* not so long ago, who explained that one of the principal drivers for Dave B is that there is a significant deck training and currency issue with CTOL. A USN CAG requires more time to workup and retain deck currency (than the prospective CVF CAG) because trap landings are more difficult. As a result, the USN pilots spend more time working around the deck and have less time on the range. He quoted that USAF bombing accuracy is far superior to the USN, giving this as the reason.
So Dave B will give more operational availability and better bombing.
His argument not mine! So don't give me both barrels!
But an interesting perspective nonetheless.
