Agreed. Any of those places will give you excellent training. More important, though, may be what you see yourself doing before landing a job. Do you have a specific fellowship in mind? Is there a subspecialty of pathology that interests you the most? If so, look into the fellowships offered at each of the institutions, as many places choose their own fellows first. Not that you couldn't get an outside fellowship having come from any of those institutions, but it's always easier and simpler to take an inside spot. Just my two cents.
