I ate similar meals at McDonald's and Burger King to see which would do it better, and the smaller chain beat out the bigger one by a hair

I went to a Burger King in the Financial District of Manhattan, New York.

Inside was a cozy, modern space with large windows and red vinyl seating.

This was a newer location, so it came with self-ordering kiosks. Other chains like McDonald's and Wendy's also have these at their newer locations.

But I just ordered the old-fashioned way: at the counter.

I ordered a Whopper with cheese and made it a meal ($9.69 before tax).

Pricing is accurate to the Manhattan locations I went to.

Burger King's fries are, in my opinion, severely underrated.

They're thicker than McDonald's fries but just as crispy outside, and they have a lovely soft interior.

These weren't the best Burger King fries I'd had. The texture inside was oddly sticky.

But in general, I'd take a Burger King fry over a McDonald's fry any day.

Unlike the Big Mac, the Whopper doesn't come with cheese unless you add it. So, I added it.

The Whopper is a whale of a burger. It's both wider and heavier than the Big Mac.

It's also more of a classic burger, with the standard stack of lettuce, tomato, onion, and pickle on a patty.

There's also no extra bun in the middle — a big bonus in my book.

It's a dense, crunchy, well-textured bite.

The sour, crunchy pickle slices and crisp raw onion make all the difference.

It's flavorful and it's solid — maybe a little too solid.

The thick patty tastes distinctly of charcoal and smoke, and it's not nuked to oblivion. It's okay.

But really, it's the veggies that balance out the beef and make the burger appetizing.

Still, at a certain point, the heaviness of the Whopper began to weigh on my stomach.

I went for a couple more fries before packing up my leftovers.

Even though I was stuffed, my bag was still full and heavy. One Whopper meal could easily feed two.

I went to a McDonald's located across the street from Business Insider's New York office.

It was a larger, older location than the Burger King I'd gone to.

While newer McDonald's have ordering kiosks, this one's technology was a little more old-fashioned.

Every McDonald's looks slightly different. This one looked like the inside of a spaceship.

I grabbed my food and found a table upstairs.

I got a medium Big Mac meal ($9.79 before tax).

McDonald's fries are THE fries for many people, but not for me.

If you need to use a "trick" like ordering unsalted fries to get good fries, the fries weren't that good to begin with.

McDonald's fries are salty and crispy, but they're thin and lacking flavor or substance.

The salt and the crisp — that's all they have. None of that lovely inner gooeyness you get from a thicker potato.

McD's fries ultimately just taste like cardboard.

There's a brief moment of satisfaction the moment they hit your tongue, but that dissipates as quickly as the fries lose heat — which is quickly.

I found the pleasures of the Big Mac to be equally hollow and fleeting.

Why, oh why, does this burger have a third bun in the middle? Buns don't add flavor, just structure.

The Big Mac is exceedingly beige, beefy, and bready, and its ingredients separately are all unremarkable.

The only thing that makes the Big Mac taste like anything is the signature Big Mac sauce, a slightly sour, creamy take on Thousand Island dressing.

But compared to the Whopper, eating a Big Mac is like eating a big cloud of nothing.

There's no veggie crunch, no pungent onion, no leafy lettuce. The beef is also very mild. But the sauce is distinct.

So which burger behemoth bested the other in this bite-off?

If I was stuck on a desert island that only had a Burger King and a McDonald's and nothing else, not even coconuts, I'd choose Burger King — but just barely — for its better fries and more balanced burger.

But honestly, my body felt like total crap after both meals. All I wanted to do afterward was dive into a pile of salad. Given the choice, I'd choose neither chain.
