Greg I am pretty sure that a manual Mach red-lines at the same RPMs as the 99/01 Cobras. I know for a fact that the red-line is lower for the auto versions though. There is a general consensus that the Mach has less upper range power than the 99/01 Cobra but I am not fully sold as I have seen over-laid dyno graphs of 99/01 Cobra and Mach curves and the upper range was about the same, but the mid and low range of the Mach was significantly better than the 99/01 Cobra. However a very proven combo is the 03-04 heads and the 99/01 cams. There is also some speculation that the casting quality of the Mach intake is better than the 99/01 Cobra.
Finally, the seats in the Mach are retro designed and I think they are sweet. I believe that they are modeled after the "Comfort Weave" seats of the 69-70 Mach. Also the numbers on the dash are retro.
