10 Burger Chains Ranked By Customer Satisfaction: The Latest Scores And Loyalty Standouts

Spread the love

Everyone has a burger-chain opinion.

Maybe you swear by Five Guys fries. Maybe an In-N-Out Double-Double is non-negotiable whenever you’re near one. Maybe you’ll defend the Whopper with the kind of passion usually reserved for sports teams.

But customer satisfaction is a little different from having a favorite burger. It includes the whole experience: food quality, value, service, accuracy, speed, convenience, and whether customers leave feeling the meal was worth their money.

The latest American Customer Satisfaction Index, or ACSI, gives us a useful snapshot of how major burger chains are performing. Its 2026 restaurant study surveyed 16,464 customers between April 2025 and March 2026 and scored brands on a 100-point scale.

One catch: ACSI publicly scored only seven individual burger chains. So the first seven spots below come directly from that apples-to-apples comparison. The final three are notable performers from Market Force’s separate customer-loyalty research, which uses a different methodology and should not be compared numerically with ACSI scores.

With that important disclaimer out of the way, grab the ketchup.

Culver’s

Culver’s tied for the highest score among the burger chains ACSI measured, earning 78 out of 100 and holding steady from the previous year.

That is especially impressive considering Culver’s competes against chains with dramatically larger national footprints. ACSI highlighted qualities including fresh, made-to-order food, friendly service and a broad menu.

In other words, Culver’s seems to understand that burger satisfaction isn’t just about the burger. Getting the order right, treating people well, and serving food that feels freshly prepared all count.

Burger King

Burger King also scored 78 out of 100, tying Culver’s for the top spot.

If that surprises you, you’re probably not alone. Burger King improved from 77 to 78, with ACSI pointing to its “Reclaim the Flame” turnaround strategy, restaurant remodeling, Whopper updates, broader menu choices, and a more family-focused approach.

The interesting part is the scale. Burger King operates thousands more U.S. locations than Culver’s, yet managed the same satisfaction score.

That said, both chains were still one point below the overall quick-service restaurant benchmark of 79.

Sonic Drive-In

Sonic earns the “most improved” trophy.

Its score jumped from 73 to 77, the biggest year-over-year increase among the burger chains measured by ACSI.

Value offerings appear to have helped, while Sonic’s beverage-heavy menu gives it another way to stand out. Anyone who has looked at a Sonic drink menu knows the company does not believe beverages need to be boring.

Still, a score of 77 leaves Sonic slightly below the broader quick-service average.

Wendy’s

Wendy’s tied Sonic with a score of 77, improving from 75 the previous year.

That puts it only one point behind the two category leaders and comfortably ahead of several larger competitors.

One important caution: ACSI does not publish detailed Wendy’s-specific scores for things like speed, staff friendliness, or food quality. So while overall satisfaction clearly improved, we can’t confidently point to one factor and call it the reason.

What we can say is that Wendy’s is moving in the right direction.

Five Guys

Five Guys is where things get interesting.

Its ACSI score rose slightly from 75 to 76, but it still sits below the overall quick-service average of 79.

At the same time, Market Force has placed Five Guys among its top burger brands for customer loyalty.

Those findings are not necessarily contradictory. ACSI measures overall customer satisfaction using its own model, while Market Force also considers factors such as recommendation and return intentions.

That makes Five Guys a fascinating example of a brand customers can feel strongly loyal to even when its broader satisfaction score isn’t at the top of the category.

Jack in the Box

Jack in the Box stayed flat at 74.

That puts it near the bottom among the seven named burger chains in ACSI’s latest rankings and five points below the overall quick-service benchmark.

Its competitors also make that unchanged score stand out more. Sonic rose sharply, Wendy’s improved, and even McDonald’s gained ground.

Standing still can feel a lot like falling behind when everyone else is moving.

McDonald’s

Here’s the biggest reminder that popularity and satisfaction aren’t the same thing.

McDonald’s scored 72, the lowest among the seven burger chains measured by ACSI. It did improve from 70 the previous year, but it remained seven points below the overall quick-service average.

And yet McDonald’s remains enormous. QSR’s 2026 rankings put its 2025 U.S. systemwide sales at more than $55 billion across 13,706 U.S. restaurants.

So no, a low satisfaction score does not mean nobody is eating there.

It means market dominance, convenience, and sales volume do not automatically translate into the highest-rated customer experience.

In-N-Out Burger

Now we switch data sets.

Market Force placed In-N-Out among five leading burger brands on its Customer Loyalty Index, with that group scoring between 4.5 and 4.67 out of 5.

The exact chain-specific score was not publicly disclosed, and In-N-Out did not receive an individual 2026 ACSI score, so it would be misleading to claim it beat Culver’s or Burger King.

Still, its presence among Market Force’s strongest loyalty brands confirms that customers remain highly enthusiastic.

Freddy’s Frozen Custard & Steakburgers

Freddy’s also appeared in Market Force’s elite burger group.

That makes it an interesting example of a smaller operator building unusually strong customer loyalty without the footprint of giants such as Burger King or McDonald’s.

Market Force’s public release does not provide Freddy’s exact score, so the takeaway is that it ranked among the strongest-performing burger brands in the study.

The Habit Burger Grill

The Habit rounds out the list as another Market Force top-five burger brand.

Like Freddy’s and In-N-Out, its exact score was not publicly released. The research does show it performed strongly on an index combining satisfaction and likelihood to recommend.

That is noteworthy because it shows customer enthusiasm isn’t limited to the biggest, most widely available chains.

What Customers Actually Care About

Perhaps the most useful takeaway from the ACSI research is that satisfaction comes from a bundle of small things done well.

Order accuracy scored an impressive 87 out of 100 across quick-service restaurants. Loyalty-program benefits scored 85, while food quality, staff courtesy, cleanliness, digital experience, and checkout or delivery speed were all important parts of the customer experience.

Price matters too. In open-ended customer feedback, lower pricing was the leading request for improvement, followed by faster service, better accuracy, and improved food quality.

So the winning formula isn’t simply “be cheap.”

Customers seem to want value: good food, the correct order, reasonable speed, friendly service, and a price that feels justified.

And perhaps that explains the biggest surprise in these rankings. The burger business isn’t automatically won by the chain with the most restaurants or the biggest advertising budget.

Sometimes, it’s won one accurate order, hot burger, and friendly interaction at a time.
