This are guys Buffy met at least once, some where nice, some not, but all of them didn't last in Buffy's life. If you could choose one and change the course of their history, who would he be and how would you develop their relationship? My vote goes to Owen. I think he was good looking and nice. I can see him being one of the scoobies, helping with the research work and eventually learning to fight at Buffy's side.
