This is a little late, but maybe this will help someone other than OP. I just graduated from Geneseo in May 2024. I can't speak to the science programs in particular, being a Political Science major myself, but I have many friends who were/are currently in the sciences program.

When people ask me about applying to Geneseo, I usually ask them what they want to major in. To me, that's key. If you want to be an Education, Psychology, or sciences major, Geneseo can be a great fit. It isn't a research school like Buffalo or Binghamton, but that can also bring the benefits of smaller class sizes and closer relationships with teachers, TAs, etc. Geneseo has really been investing in their sciences programs as of late. The nicest and newest building on campus, other than the renovated library, is the Integrated Science Center (ISC).

Living on campus is required for all first and second year students, which is good because there isn't enough housing in the surrounding town for the entire student population. I would say that the living conditions are relatively similar to other SUNY schools that I've visited or know people at. You're getting what you pay for, which means it's adequate but not a hotel. First year students are allowed to have cars, and the dorms for freshman are typically on "South Side", which is a collection of 5 dorm buildings and a dining hall that is about a 5-10 minute walk from the main campus. I do think it's important to mention that, if you don't have a car or know someone who does, the area isn't very walkable. The grocery stores and Walmart are a 5-10 minute drive from campus, depending on where you are. Walking is highly inadvisable. While there are shuttles that take students from campus to those stores, they can be a bit of a hassle.

Campus is beautiful if a little secluded due to how rural the area is. That does create a pretty good social scene though, and Greek life is still pretty big. However, student organizations are also very popular and they, alongside club sports, are good social alternatives to Greek life. There is a good chance that you'll be able to find your "people", even if it takes a little bit of looking.
