Yahoo tends to convert slightly better, but google has a much higher volume of searches and is much more popular, for people with a low budget, I would recommend Yahoo.
I think it will depend a lot on the niche, but I never had much luck with yahoo. Google has brought me a lot more traffic, and I think the AW interface is much easier to understand than the yahoo version. I may use yahoo again for some other sites in the future, but right now Google AW is working the best for me.
