In today's quarter-final match-up of The Motley Fool Better-Buy Tournament, CONSOL Energy squares off against InvenSense in a battle to determine which stock is the better buy now. The 64-company tournament pits two Motley Fool analysts against each as they make the case for their stocks with the winner determined by you, the readers.

Motley Fool energy analyst Taylor Muckerman thinks CONSOL Energy (CNX) should move to the next round because of its accelerating shift into natural gas. While it might be the oldest coal producer in the nation, natural gas is CONSOL's future. To avoid being blindsided, though, CONSOL wisely chose to hold onto its lower-cost thermal coal mines and its solely owned export terminal as a nice hedge while the market shakes itself out. Other coal companies are likely jealous of this flexibility, so don't be jealous if CONSOL moves on.

InvenSense (INVN) is the better buy today for two big reasons. First, more than 7 billion mobile devices will hit the market over the next five years. And the expectations for the wearables market are even larger. All of those devices will need sensors, and InvenSense will be there to supply them. The company designs accelerometers, gyroscopes, and microphones and packages them in various combinations with tiny processors, bringing incredible functionality to users. Management expects sales growth in 2014 to be 25%-35%. Motley Fool analyst Dave Meier expects the stock price to respond in kind, making it the better buy today.
