I would say BU, GW, BC and NYU are about on the same level reputation-wise. They have similar acceptance rates and rankings- with a few exceptions.
Also, it is not safe to assume that schools of higher reputation are also schools in which achieving a higher GPA is more difficult, forget about exceptions to your rule. This is especially true when you consider that half of the Ivies have grade inflation.
I agree with most of @chrisw 's point, except for the Goldman Sachs/LAC part. A better way to look at Goldman Sachs and other top IB/finance recruiting is to look at their target schools- and this includes some LACs, such as Williams and Amherst (which proportionally do much better in IB placements than almost any other school).
