Pretty good climber....

F6F is compared to SBD....

Neither one of those sentences should ever have been uttered....

EDIT: On second thought I think I should add something to this topic. The SBD is a throwback design from before WW2. At the time slow stall speed was the main criteria. Performance and capability weren't tops early on, it was functionality. The need to actually launch and retrieve craft and stow them under decks took precedence. This meant emphasis was put into light weight, small airframes, with slow stalling speeds for easier takeoff and landings. As it was, they still often had to take off into the wind. Remember in WW2 you took off from the front of the deck only, all the deck behind you being full of your neighboring squads and pilots wating for you to get out of the way. Now try doing it with a bomb onboard!
The reason the SBD is "nimble" (and I think that's a wrong claim... It's not very nimble, it only has a small turning radius -- there is a difference) is because it is light weight and has a low stalling speed.
HOWEVER much like the Japanese aircraft this light weight and low stall speed was achieved by sacrificing engine power and weight. You cannot increase performance on the SBD without increasing weight of the engine, which then raises stall speed and all of a sudden it can't turn, can't carry bombs off a deck, and can't do its job.
It's a balance. There is a very fine line between weight, size, engine power, and actual performance. The solution to get a better plane wasn't to stick a R2800 onto the SBD, but rather re-evaluate the ever changing needs of war and come up with a modern design that properly fits those needs.
