In the spirit of World Cup competition, we're holding our own tournament in search of the Better Stock Today. We're pitting 32 companies against each other and you, the reader, will determine the winner.

InvenSense (NYSE:INVN) takes on SodaStream (NASDAQ:SODA) for this first round-robin match-up in our search for the better stock today.

Tech analyst Max Macaluso believes one of the top reasons to be an InvenSense bull today has to do with the company's tremendous growth potential. This sensor specialist has already benefited from wider adoption of mobile devices, and looks poised to also benefit from the growing wearable technology trend. Couple that with its dedication to research and development, and InvenSense can be a market leader over the long-term.

Mark Reeth, consumer goods analyst, believes the No. 1 reason SodaStream should win this match is the fact that it's undervalued. With shares down 25%, SodaStream has presented investors with a great buying opportunity. While the company didn't give investors the same growth rates it usually does in the U.S., it's still performing well in its other markets. There's no reason it won't continue to see success in those markets, and it'll likely return to form in the U.S. over the course of the year. Meanwhile, Coca-Cola and Keurig are a long way from perfecting their cold-beverage device, but SodaStream's already got it figured out and isn't going anywhere.
