Stock Madness, like March Madness, is a game of matchups. So how does Starbucks (NASDAQ:SBUX) match up with fellow Stock Advisor pick Whole Foods (NASDAQ:WFMI)? Pretty well, I'd say.

Sure, Whole Foods has made some modest improvements since 2003, but Starbucks is up dramatically. Just look at the returns on capital (ROC).

Nevertheless, investors would be hard pressed to tell the difference between these two recently. Both have lost to the market since early 2005. That might be fair if Starbucks were performing as inconsistently as Whole Foods is.

An offense in disarray
But that's not the case. To the contrary, Starbucks is improving dramatically. ROC was up another 1.7 percentage points over the most recent quarter's trailing-12-month period. Whole Foods, meanwhile, is about to spend $565 million to inherit the mess that is Wild Oats (NASDAQ:OATS). Have a look at how the amateur and professional investors participating in our Motley Fool CAPS investor-intelligence database rate the stock:

For his part, Whole Foods CEO John Mackey says he'll add "jet propulsion" to some Wild Oats stores. That sounds good. But you have no idea how difficult that will be -- unless, that is, you've actually shopped at a Wild Oats, as I have.

We frequent a local Wild Oats to get safe products for our food-allergic boys. Trouble is, it's a hit-or-miss experience that's rife with far too many misses. Need gluten- and lactose-free potato bites? Try again Saturday. Organic scone mix? See you Wednesday.

My point here is that Wild Oats is nothing like Whole Foods; it simply doesn't have the inventory. That's a huge problem that will take significant capital to fix. Expect Mackey to spend it.

But to earn the returns that he and Whole Foods investors are looking for, he'll undoubtedly raise prices at every Wild Oats store that remains open. Don't be surprised if that sends patrons who can't afford to spend a whole paycheck on groceries to the aisles of Kroger and Safeway.

Points in the paint
But let's get back to the matchup. Starbucks and Whole Foods are similar in many ways. Both have very Foolish leaders. Both create top-notch experiences that draw loyal customers. Both are environmentally friendly. Both sell healthy foods. And both have earned spots on Fortune's list of the "Most Admired" companies.

Oh, wait, that's just Starbucks. It ranked No. 2 behind General Electric (NYSE:GE) in the latest list. Perhaps that's because, unlike Whole Foods, its competition from Caribou Coffee (NASDAQ:CBOU), Peet's (NASDAQ:PEET), and Green Mountain Coffee Roasters (NASDAQ:GMCR) is comparatively weak?

Scoreboard
As the buzzer sounds, what ultimately matters is valuation relative to growth prospects. Here, too, Starbucks wins. Analysts give the coffee king a current PEG -- a measure that compares the P/E ratio to projected growth -- of 1.57. Whole Foods, meanwhile, comes in at 1.80. That's a substantial difference and, according to research, it's not to be easily dismissed.
