I've only visited and toured Elmira from this list, and it is a tiny perfect school if what you want is a small school with small classes, and you can afford it. The prettiest, oldest campus with great architecture, an optional third semester, and two particularly special programs - freshman writing and encore.
Utica also impressed me for its new criminal justice facilities and programs for the serious future computer fraud fighters and forensic experts, and Norwich if the military is your bent.
Plattsburgh was also all-round good value and nice environment between the lake and the mountains; I liked the smidgeon of French influence there.
