Top two picks from each row:

• McDonalds is a standard, but I prefer Arby's seasoned curly fries
• Wendy's recently changed their fries and they're good enough, but prefer Smash fries.
• (Special mention goes to Canadian KCF, which offers fries and gravy instead of mashed potatoes and gravy. I don't know if their US fries are different because I don't mess with that if mashed 'taters are an option.)
• Five guys and Checkers
• Steak 'n Shake and Popeyes

Overall, if I were choosing a place based solely on the fries: Smash > Five Guys > Popeyes > Arby's

The top two spots were tricky. I like the 5 guys fresh cut style, but Smash mixes a traditional thin cut fast food fry with rosemary. And they don't make things weird by giving you more than you can or should eat.

The only one I actively dislike is Chick-fil-A, but some of the other offerings are 'meh' enough that they need ketchup.

Missing entries: Penn Station and Skyline. They're both regional, but I like both of them over most of the other offerings. Penn Station has fresh-cut style and Skyline's fries are thin and crispy.
