I tried the signature burgers from McDonald's, Wendy's, and Burger King. I found the Big Mac underwhelming.

• I tried the signature burgers from three fast-food chains: McDonald's, Wendy's, and Burger King.
• I thought McDonald's Big Mac was underwhelming and needed more sauce.
• I liked the smoky flavor of Burger King's Whopper, even though it was the priciest burger.

As a fast-food reporter, I've tried and tested many fast-food burgers over the years.
