That is tough.

Cowboys probably have the worse D, although Lions secondary sucks, but Boys should be playing from behind a lot again this year. Plus, everyone's D in their division sucks so Romo should have success. Scott Linehan is the new play caller this year and he likes to go vertical. While in Detroit they are getting the great grandson of Vince Lombardi to get his first shot as OC after being positional coach in N.O. But he should be ready getting valuable experience learning from Peyton and Brees. Also, the Lions have a new HC in Jim Caldwell.

There are a lot of similarities in both offenses from Megatron to Dez. Witten to Lions rookie TE Eric Ebron. Both have very capable 2nd and 3rd WR's as well. Along with good Recieving backs Bush and Murray who had 53 receptions last year.
Surprisingly, Romo has never hit 40 TD's in a season where Stafford has done it once in his short career but then dipped back down and never got close since.

One thing to take into account is the schedules, Stafford has to play @ Chicago outside in December week 16 for what would be your Championship game.
Romo is home for the Colts.

I think you should be able to say, Stafford and want to say Stafford. But I'd go Romo still one more year.
