Well specifically with regard to air-to-ground bombing, does the plane actually "matter", in the big picture, to the success of a bombing strike?
As we've mentioned, dogfighting is all about energy, and the planes designs and powerplants were key to their performance in the air.
But for the bombers? Particularly dive bombers, was one dive bomber dramatically different from another? If the payload was the same, would a Dauntless be better, in the attack scenario, than, say, a Stuka. The basic technique was, literally, dive on the target, very high angle of attack, I imagine line up some sighting device on to the X, and release the bomb.
Now, afterwards, the performance of the plane may affect how fast it can pull up, how high it must release from, how fast it can get out of the defensive AA bubble of the target. And, of course, there's pilot skills (as well as temerity to hold the line and push the attack with explosions going on all around your head).
But, all said, would a Dauntless have a 50% chance of an on target success vs a Stuka that might have a 40% chance? (Just making up numbers, what do I know about dive bombers?). Similarly with torpedo bombers.
The A-10 excels in ground attack if for no other reason that it can come in slower to keep on target compared to an F-16. That makes it, perhaps, easier to make a successful attack (at least a gun run) with an A-10, perhaps, than an F-16. But most modern ordnance delivery is well influenced by the computers. I dunno if an A-10 is better at delivering a 250lb bomb than an F-16.
