I myself tend to think due to her training her reflexes are better than Superman's. I'm sure some measure it based off of feats but I honestly don't see Superman being able to blitz her effectively due to her reflexes but he's got the power/strength advantage along with being more durable. In the end I think people are split down the middle.
Her combat skill makes her more effective in close quarters than he, but reflexes in the general sense can be argued either way with raw speed output belonging to Kal. Still, it doesn't make her untouchable nor does it make her able to hit without fear of retaliation when you look at comics instead of trying to force how you think comics should work.
It's a statement; I would have looked at feats as a whole to see if they matched up. I don't take statements at face value.
I have a tremendous amount of knowledge and respect for Diana, and I know that Kal has more than enough reflex feats to argue the point. It's Diana's application of said reflexes in a combat situation is where she shines versus Kal, not just reflexes, period.
It's not about how comics should work but how comics work when they work according to what makes more sense.
Comics support both sides. But since characters fight at their best then we are forced to choose the more logical side of what comics show us.
Comics show Diana ducking from ultra fast Superman punches from close range, Thanos using the combo to ko principle, Superman using speed to make his enemies like statues, etc.
Also WW shows that she is in the vicinity of Superman's strength when Superman doesn't affect Konvict and she does here:
Looks like a Thor hammer blow without using a hammer.
Then there is a feat where she overpowers Supergirl when Supergirl can't control her powers (everyone claimed she was stronger than Superman at the time).
So how come this "fighting at their best" thing seems to only favor speed based showing?
Fighting at his best, Thor is beyond Diana, and has the speed to ensure he can adequately defend himself, make offensive attacks, as well as tactics to get around his inferior speed. He quite simply operates on a larger scale than she when the chips are down.
No Thor doesn't have adequate speed to defend against Diana's speed, just slower moving being's speed. Every time in comics that someone used great speed on Thor then he got either messed up or embarrassed. And Diana is an excellent counter attacker.
Fighting at best ALWAYS favors the fastest and most skilled characters.
In the scan Superman failed to affect Konvict with his blow, yet Diana rocked the hell out of him. I'm not saying she is stronger than Supes. But the feat supports that she isn't too far off.
Thor seems stronger because of that gotdamn hammer. He hits with mighty blows because of it. It's an illusion I tell you.
