I tried the same chicken sandwich at McDonald's and Chick-fil-A, and I'd stick with the cheaper one next time

Both sandwiches came in foil bags. They also both stayed warm despite half an hour passing between the time I picked them up and when I finally got them home. 

I noticed that each sandwich had a very different bun. McDonald's bun, pictured on the right, was harder and slightly denser, while Chick-fil-A's was softer and slightly bigger than the fillet inside.

The chicken sandwich from Chick-fil-A cost me $8.65 at my local Chick-fil-A in New York City, making it slightly more expensive than the McDonald's sandwich. 

Chick-fil-A has consistently ranked as one of America's biggest fast-food chains, and customer loyalty is high. 

"Chick-fil-A has very strong brand loyalists," former McDonald's chef Mike Haracz told Business Insider. "I've sat in panels when I was doing chicken work. They will try the food, but when you tell them it's not from Chick-fil-A they'll say, 'Well, I think it's great but I'm not going to buy it because I am a Chick-fil-A consumer.'"

However, Haracz said that "there are some people who might go to Chick-fil-A strictly for the flavor" alone, and if McDonald's can match that, they may be swayed.

Chicken sandwiches have been mainstays on most fast-food menus since 2020, but Chick-fil-A is often considered the original.

The chain also consistently outperforms its competitors. A recent ranking by Technomic ranks Chick-fil-A as the biggest chicken-focused fast-food chain in the country and the third-biggest fast-food chain overall. McDonald's still ranks as the No. 1 biggest fast-food chain in the country.

However, at the franchisee level, Chick-fil-A might be coming out on top. CNBC recently reported that the average franchised Chick-fil-A restaurant (not including ones in malls) brings in about $8.7 million in sales each year, compared to the average franchised McDonald's restaurant, which makes about $3.7 million in annual sales.

This is especially impressive considering that unlike McDonald's, which is often open 24/7, Chick-fil-A is only open six days a week. 

Chick-fil-A's chicken breast was flakier rather than juicy. Looking at both of the sandwiches, the fillet itself also looked slightly bigger. The breading was thinner and clung to the chicken breast well, which gave it a great texture. 

However, I was slightly disappointed by Chick-fil-A's pickles — they didn't have the strong briny flavor or crunchiness I usually look for.

The McDonald's crispy chicken sandwich cost $7.49 at my local chain in Brooklyn, New York.

I've been a fan of McDonald's chicken sandwiches for years, but I could already tell that I was going to like this new sandwich a lot more.

The bun held the contents of the sandwich together perfectly, and in terms of size, I thought McDonald's did a great job at nailing the bun-to-chicken ratio. 

The sandwich's breading had a slight sweetness. However, the tart, crunchy pickles, which had a strong briny flavor, perfectly balanced it out. The chicken was thick, juicy, and flavorful.

The only aspect of the sandwich I wasn't in love with was the bun — though it was a good size, I thought it was slightly too thick. I'm of the opinion that a sandwich bun's sole purpose is to hold everything together, without overpowering the other ingredients. I think this thicker potato bun slightly missed the mark on that.

So, how similar were the two sandwiches? Pretty similar, in my opinion. If I was to do a blind taste test, I might not even know which was which, unless one was slathered in Chick-fil-A sauce. However, this is not to say that McDonald's is actively trying to copy or imitate Chick-fil-A's most iconic offering.

There is a trend in what consumers are looking for in a chicken sandwich, whether they're ordering from Chick-fil-A, McDonald's, Popeyes, or any other chain.

Judging by the success of the chicken-war competitors, consumers want a Southern-inspired flavor with juicy, flavorful chicken and tart and crunchy pickles. McDonald's definitely delivered on all counts.

As far as this food reporter is concerned, the McDonald's chicken sandwich stacks up well against fan favorites — and you save a little bit of money by ordering from the bigger chain.
