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 takes on Johnson & Johnson 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 (NYSE:INVN) 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.

Health-care analyst David Williamson believes the No. 1 reason Johnson & Johnson (NYSE:JNJ) should win this match is its diversification. The health-care conglomerate has one of the strongest pharmaceutical divisions in the industry, regularly posting double-digit growth and rolling out exciting drugs like Imbruvica. J&J's medical device unit is still benefiting from the massive $21 billion Synthes acquisition, and its consumer unit has a strong exposure to fast-growing emerging markets. Add in a stable dividend, and investors have a solid defensive stock with nice pharma upside.
