I’m not familiar with Rochester but am very familiar with Grinnell. Compared with other LACs, Grinnell’s student mix is very international. While the location is fairly remote, the campus culture is vibrant and cosmopolitan. One of Grinnell’s strengths is the availability of research opportunities. Physics and CS are both strong departments. Graduates do very well in the employment market (especially CS and physics majors), so have no worries there. The alumni network is spread worldwide and very loyal. Grinnell is highly respected by top grad school programs. If you are interested in internships nearby during the school year, Des Moines provides many excellent opportunities. Over the summers, students find top internships anywhere or you can do research on campus. Grinnell does excellent reporting on student outcomes (employment, grad school choices, research, internships, location of graduates, etc.).
