But the main competition seems to be between Popeyes and Chick-fil-A.
Although Chick-fil-A has been famous for its chicken sandwich for decades, Popeyes’ version of the dish has threatened to take the top spot.
Some posted videos of their first impression of the Popeyes sandwich.
Others said the entree was sold out or revealed the lines were long at their local Popeyes thanks to hashtags like #ChickenSandwichTwitter or #ChickenSandwichWar.
A few said making the switch to Popeyes was easy because of Chick-fil-A's stance on gay marriage. The brand's CEO, Dan Cathy, said in 2012 Chick-fil-A believed marriage to be between a man and a woman, citing the family's Christian beliefs.
But many remained loyal to Chick-fil-A and said the chain was the reigning champ of the chicken sandwich.
