We tried KFC and its biggest fried chicken competitor - and the winner is clear

With 2014 US sales topping $4.2 billion, KFC is second only to Chick-fil-A in the fast-food chicken segment.

But its largest competitor, Popeyes, is closing in, coming in at number three on the fast-food chicken list at $2.4 billion in US sales.

But business aside, there's one thing that truly matters: the food.

Both chains are indisputably at the top of the fried chicken sector, but who does it best?

KFC has the advantage of time: their secret blend of herbs and spices has enjoyed 75 years worth of perfecting. Yet Popeyes' Cajun approach, be it mild or spicy, has staunch support.

And of course, one can't try fried chicken without considering the sides.
