I don't think it's the code superiority that decided the fate of the two schedulers. When CFS came out, the fate of SD was pretty much already decided. The fact is that Linus trusts Ingo, and as such he wants to merge Ingo's code. Of course I cannot say it's wrong, and Ingo's earned this it through years of hard work, but let's not kid ourselves and deny the obvious fact.
I agree with you here. It's not simply code superiority that matters but a balance of attitude and the code's corroboration with numbers. Both had numbers to show but I think that one's attitude was preferred over the other.
I think Con was simply too frustrated after years of rejection. He could have been more diplomatic this time round. But no matter how he'd have done, once Ingo decided to write a new scheduler, the outcome was pretty much already decided. SD (and years of Con's work) inspired CFS. This is a fact. No matter how smart and capable Ingo is, he needs inspiration to keep the good work going. So I wish Ingo could work more closely with others and let them share a bit more credit which would just produce even better work.
I don't see where credit was lacking. As far as I've observed, SD's author was given acknowledgment on what he did and even got praise.
