My thoughts are similar. It's as much about the lifter as the lobe profile.
My guess is that the fast rate would probably make more peak if the lifter stays compliant. But if it starts to give it up after peak, the old school still might have greater average hp/area under the curve, ie making the car faster.
My 383 with the new hemi grind and 30 year old lifter will pull decent to 7000 rpm, despite peak power probably at 6000-6200.
