Actually, Flay is the most competitive, as well as being the most combatant. But, Batali is more skilled and creative. Big difference between skill and competitiveness.
At first, I'll admit that I got a few ideas from Flay regarding the usages of different ground, whole, and dried chiles. But that was YEARS ago. Flay is doing the same stuff that he did in the mid to late 90's at Mesa and Bolo. C'mon, quesadillas, stuffed peppers, blooming onions?
Batali on the otherhand, has really evolved in both his technique and his usage of various types of ingredients and cuisines. He shows that he's so much more than just Italian and Mediterranean flavors. He's also shown that he's able to perform outside and above his comfort zone with the different flavors he brings to the table at every match he's in.
