After somewhat mixed years in 2012, shares of both Facebook (META 1.54%) and Netflix (NFLX -0.51%) have exploded so far in 2013.

For Facebook, the company has shaken off its post-IPO hangover by largely solving its problems on mobile and also rolling out several intriguing ad products that once again have investors excited about the social-networking giant's massive potential. In a somewhat similar storyline, Netflix has also found a way to solve some of its most significant criticisms. It created a powerful means of differentiating itself from an increasingly crowded field of streaming services by producing several hit original series of its own. Shareholders have rewarded both companies handsomely as a result.

Facebook and Netflix are currently trading close to their all-time highs, but they still hold plenty of future promise. So which is the better buy today? In this video, tech and telecom analyst Andrew Tonner gives his pick between these two growth-stock superstars.
