Personally if it is a used car, I would go with a Mach 1. The reason being is that it is rare compared to the 05+ GT.
For those of you who think that the 05+GT is heavy some food for thought. From my own personal experience with Mach 1's. Personally I think the 05+ Mustang is better looking than the 94 - 04 models.
On the same day, same scale, right after the other, I weighed my 05 GT and my buddy weiged his 04 Mach 1. Both of our cars have 5 spd manuals and had full tanks of gas, full weight, completely stock, no driver or people in either car. My car weighed 3476 lbs to his 3488 lbs. The newer GT's are not as heavy as you think they are and the Mach 1 is not as light as you think. The Mach 1 was fully loaded, my car has these options:
4.6L 3V
5 Spd TR 3650
IUP
Active anti-theft
Leather seats
Shaker 500
Bullitt wheels
Side Airbags
Had I ordered the Shaker 1000 stereo system, it would have added some weight.
As for which one is faster, my buddies Mach 1 *feels* faster but in reality, his car ran slower than mine did side by side at a 1/4 track. With me driving his car, I got it to run within 3 tenths of a second of what my best was with my GT is. That is the best pass his car has run to date, 3 tenths slower than mine, and it was done the same day as I ran my best.
Some more food for thought. This is the mod list of a 04 Mach 1 that is a registered member at Stangnet and runs his car at the same track I go to. I am posting his signature.
My 05 GT has run 13.7 @ 101 with just a SLP axleback and MT ET street radials.
I do believe that it is a driver's race between the 2. I have a few Mach 1 owners that have 05+ GT's as well and they all say the same thing.
