Assuming that we are looking at both in their prime the answer is simple; Jack O'Neill.
If we're looking at the moment then we have to recognise that General Jack O'Neill is already fighting a battle and losing badly. It was a well versed fact that at junior ranks Jack would only attend meetings and briefings if there was cake. Now he is a general he is obviously attending meetings and briefings all the time. In short he'd have to win his battle against cake before being able to face off against Sheppard.
In their prime it would be a close matched thing. Both are used to improvising in tight situations but Jack's dark past, range of experience and well hidden darkness would win in the end.
In "Stargate SG-1", Colonel Jack O'Neill becomes a general and is promoted to the head of Stargate Command. Over the course of the series, he faces various challenges and adversaries while leading his team on missions through the Stargate to explore new worlds and defend Earth.

No, Sam never does get married. The good thing is that in a season 4 deleted seen of Stargate Atlantis, she is talking to Dr.Kellar and she tells her that she(Sam) has someone back in the United States. Crossing my fingers that the person is Jack O'Neill. She also has a picture of Jack in her room in Atlantis.
