The SOC3 was a scouting aircraft - not an attack aircraft.
The SB2C had it's issues, but by the last half of the war, it was more than proving itself.
I'm well aware the SO3C was a scout plane (and rescue, ASW etc.) but scout planes were pretty important in WW2 naval combat. Especially for the Americans who really needed their heavy gun-ships (BB's, BC's, CA's and CL's) since their torpedoes didn't work in the first year or two of the war, rendering Destroyers severely weakened in terms of effectiveness.
Also lets be real, scouting, maritime patrol and ASW were a big part of what some of the other planes we are discussing - Swordfish, Albacore, and postwar Gannett - actually
did in the war. The TBF sunk some enemy ships but it too spent a lot of time in this kind of role. Certainly that's all it was good for in the 50's, I wouldn't want to see one squaring off with a Mig 15.
And again, the SBD, despite the scrutiny, did turn the tide of the Pacific war through it's efforts at Midway. There is literally no other aircraft that can hold that title.
I know it's been mentioned that it wasn't the SBD but other "factors" that turned the tide of that battle, but in all honesty, when divebombers cripple and sink a fleet's compliment of carriers by themselves, "themselves" meaning no other aircraft or surface ship was involved in the sinking, then that carries weight in the SBD's favor.
I would say Coral Sea, Midway, and the Solomons campaign, not just Midway.
In addition, the SBD was one of the only dedicated divebombers to have a positive enemy aircraft kill ratio, ending up downing 136 enemy aircraft in combat.
Lethal and versatile.
SBD was one of those planes that was kind of thought of as stop-gap. In a way, similar to the Ju 87. I don't think it was ever realized in the 30's what an important role the Ju 87 was still going to play in the mid 40's.
Being reliable, lethal and versatile - and a good dive bomber, meant that it was a lot more effective than most other bombers around.
Torpedo planes were only as lethal as the torpedoes they carried, but they never had a particularly good survivability ratio and usually weren't that good at much else.
TBFs and their ilk weren't very good at attacking land targets. Fighters ended up being more useful for that... for the Americans the F4U, the F6F, the P-47, P-40, P-38 and P-51 began taking over a lot of the Tactical bombing of ground targets in the second half of the war, and only medium bombers reconfigured as strafers and skip-bombers continued in their intended role.
SBD was a limited exception, as the A-24 and particularly in Marine hands as the SBD they proved useful in ground attack, because they could hit targets better than fighters and survive sorties about as well.
