Go SUNY. Albany is a very expensive private school, and from what I heard (when I interviewed) the medical research program was disbanded (no MD/PhD anymore?). They compensate with what appears to be a strong ethics program. But still , the tuition is really high. Aside from location of the campus, downstate is a better choice overall.
If you're getting more money from the 8-yr program, take it. However, in terms of bs/md programs, the RPI/AMC Physician-Scientist Program is very prestigious and one of the oldest. It's graduated some great physicians (just do a search on the program in google). ALL of the bs/md students are in the top half of their AMC class and get some good residencies. It's also a more competitive program to get into. In terms of education, RPI bs/md will give you the most research exposure compared to any other bs/md program and is unparalleled. RPI will also give a firm grounding in the science that SUNY won't be able to. Think about money and distance from home if thats an issue. If you're getting the same out of both, take RPI/AMC.
