Going up to redline is much faster and so as acceleration.
One draw back is that you loose some momemtum or torque on uphills. Example, you maintain a speed of 75mph going up hill, you let go off the accelerator pedal for a second and floor it, you'll loose the punch and may have to downshift.
Same thing applies in Gran Turismo =)
