I'm in at Heinz and it's on my short list vs some non-quant schools as well, so I feel your pain.
If your goal is to get a Ph.D, and I'll admit, I have limited knowledge, both schools will help you. Heinz will teach you hard data analysis skill which I'd imagine will benefit your research. Syracuse will give you experience, and most importantly a reference when you apply next time. I think that is more important than the programming skills, so this non-Ph.D noob says Syracuse
