In today's ­first round matchup of The Motley Fool Better-Buy Tournament, Tesla Motors squares off against CalAmp in a battle to determine which stock is the better buy now. The 64-company tournament pits two Motley Fool analysts against each other as they make the case for their stocks, with the winner determined by you, the readers.

Tesla Motors (NASDAQ:TSLA) is riding in the fast lane, according to Motley Fool analyst Simon Erickson. The company sold more than 22,000 vehicles last year, and its Model S is now North America's best-selling vehicle in its class. The company is continuing its full-throttle growth: CEO Elon Musk recently announced plans to build a "gigafactory" that would manufacture lithium-ion batteries at a massive scale. This development could unlock a ton of opportunities and change the whole game for Tesla. Within a decade, will we still refer to it as a car company?

Motley Fool tech analyst Jamal Carnette argues that CalAmp (NASDAQ:CAMP) should to move into the next round because it provides a key role in the next big thing: the Internet of Things. Simply put, the Internet of Things is connected devices -- everywhere. A recent report from Cisco projects 50 billion connected devices by 2018. If you want to profit from the next big thing, CalAmp is your choice to advance.
