MALE DOMINANCE!!!
DOS DD was as fast or faster (if you believe Booster Gold) than DOS Superman. Current Supes hasn't improved that much in that department. And while I do agree that current Supes, physically, would make short work of this version of DD due to being overwhelmingly stronger - it isn't one-on-one. While Supes is busy dodging or tanking DD's shots, he's got to worry about not being hit by Mindless Hulk - who is in all probability stronger than Kal.
And off the top of my head, he's recently been semi-embarrassed by two bricks in the form of Konvikt and Hercules. There's probably more, but meh. Having to deal with two of them - one which possesses incredible speed - and I can't really give Supes a majority of wins here.
Though, you explained yourself nicely and I like your reasons for thinking otherwise.
