The Final Four is now set in stone, and the ultimate matchup in our own Stock Market Madness 2015 bracket is here as well. The readers have spoken, and the finals will pit energy pipeline company Kinder Morgan Inc (NYSE:KMI) against credit card processor Visa Inc (NYSE:V).

Kinder Morgan logged a mighty impressive victory against Wall Street darling Apple Inc (NASDAQ:AAPL) in the semifinals, beating the largest company in the world by a vote of 419-315. I honestly believed AAPL would win out, but underdog KMI ended up taking the cake in this one.

Visa also won its semifinal game by around 100 votes, putting a hurting on Starbucks Corporation (NASDAQ:SBUX) in a 282-185 contest. Again, I happened to think SBUX would trump Visa, but my crystal ball seems to have been a little hazy.

Let’s see how the Kinder Morgan-Visa championship game goes down:

Kinder Morgan (KMI)

KMI stock has breezed through each round of the tournament, with its closest game coming in its Elite 8 showdown with Walt Disney Co (NYSE:DIS). KMI won that one by a margin of 22%.

Though Kinder Morgan already generates $16 billion annually in revenue, the pipeline operator is still finding ways to grow: Earlier this year it shelled out $3 billion for pipeline assets from Harold Hamm. Revenue is expected to grow by about 15% this fiscal year.

The real reason investors go crazy for KMI stock, though, is it’s sizable 4.4% dividend. InvestorPlace writer Charles Sizemore hit on that point in an earlier-round matchup:

“Meanwhile, KMI is reasonably cheap, sports a dividend yield of 4.4% and is a champion of shareholder friendliness. Kinder Morgan has been a serial dividend raiser, and indicated late last year that it expected to see dividend growth of at least 10% per year over the next five years.”

Other factors look good, too: KMI was just initiated as a “buy” at Argus with a price target of $50 per share, implying upside of more than 20%. And with its CEO also recently piling up on about $4 million in stock, you can be sure management has skin in the game.

Visa (V)

Visa has the largest market share of any credit card company, with its sprawling network reaching farther than rivals MasterCard Inc (NYSE:MA) and American Express Company (NYSE:AXP). A large network is a pretty enormous advantage in the world of credit cards, as greater ubiquity tends to encourage still more merchants to accept your card. Visa’s scale also means good things for investors, since the company can operate at higher margins than its competitors.

While Visa’s 0.7% dividend yield can’t compare to Kinder Morgan’s 4.4% dividend, Visa’s financial numbers are impeccable. It has zero long-term debt on its balance sheet, and its been snapping up its own shares in stock buybacks, buying 3.1 million shares in the fourth quarter.

With the recent rollout of Apple Pay changing the way consumers buy things, Visa will likely benefit. That’s because about two-thirds of credit cards on file with iTunes are Visas, far higher than its 50% global market share.

Our Championship Pick: Kinder Morgan

Ultimately, both Kinder Morgan and Visa will be around for a long, long time, and barring an impending apocalypse, neither company is going anywhere anytime soon. But the reason KMI stock comes out on top of V stock is simple: that juicy, juicy dividend.

KMI has been rapidly growing its dividend since 2011, with is payment up more than 200% since its initial 14-cent dividend. Plus, being a stable dividend payer sure hasn’t stopped KMI stock from rallying: shares are up 28% in the last year alone.

In an era of historically low rates, it’s tough for income investors to find decent yields in the fixed income world. All the while, they’re parading around in plain sight on Wall Street. KMI earns my vote to win it all in this year’s Stock Market Madness.
