UMass Amherst vs BU for computer science: which is better overall?

For computer science specifically, UMass Amherst has the stronger overall reputation. Its CS department is widely respected in the field, it has a long-standing research presence, and among students interested in software, systems, AI, and theory, UMass is very often the school people name first between these two. BU is a good university with solid CS opportunities, but in head-to-head discussions centered on the strength of the CS program itself, UMass usually carries more weight.

One big differentiator is departmental depth. UMass Amherst is known for having a large, established CS faculty and a broad set of upper-level offerings and research areas within computer science itself. That matters because "better overall" in CS often comes down to how much serious infrastructure exists inside the major, not just whether the university as a whole is prestigious.

Another difference is how each school is perceived by people familiar with CS. Boston University has stronger name recognition with some general audiences because of its location and broader university brand, but UMass Amherst tends to have the more impressive reputation among CS students, faculty, and employers who pay attention to the discipline.

Cost and environment also shape the "overall" answer more than people expect. If you are in-state for Massachusetts, UMass can be an especially compelling choice because the CS quality is high relative to the price. BU gives you an urban Boston setting and access to the city during the school year, which is a real advantage for some students, but that does not usually outweigh UMass's edge in CS program strength itself.
