If you break down each set of triplets into sub-parts then Indi's might be better, but when you look at the whole, it's gotta go to the Cowboys.
Emmitt get's you to a consistant 3rd and 1, Aikman delivers the ball immediately after his drop and with pinpoint accuracy, and Irvin either created the seperation or just stole the ball to get the first down. Together, they would march down the field at will.
A ball control, run out the clock offense makes for a better defense. Indi scores too fast, putting their defense back out on the field faster.
