They are both great schools, congratulations! I don’t think you should rule out one over the other on CS classes alone. My impressions (I attended one of them and visited the other extensively) is that the students at Wes were interested in many things and usually had several different areas going at once. Double and triple majors, sports plus school plus theatre plus art. Swarthmore students were more focused and interested in diving deeply into their majors. Both campuses are beautiful. Wed is in a larger “town” but it’s easier to get into the big city from Swat. I think Swat takes the prize on housing and Wes on dining. Maybe if you can describe a little more about who YOU are people could give more applicable advice because truly - it’s not a clear choice between them for a generic student.
