I agree with Elmer Keith. Both use basically the same parent case (yeah, I know someone will pipe up and say the 270 is based on the 30-03 case, or that the 280's shoulder is farther forward, but the cases are basically the same), both use about the same size bullets (sure, the 280 has a larger selection on the heavy end), both hit about the same velocities with the same bullet weights, so even though Warren Page and Jack O'Connor duked it out for years over the trivial differences, I would have to say they're about the same.
