In today's match-up of The Motley Fool's Better-Buy Tournament, 3D Systems squares off against Facebook 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.

Leading 3-D printer maker 3D Systems (NYSE:DDD) has so many things going for it, argues Motley Fool analyst Sara Hov. Exponential demand has far outpaced production. Unit sales tripled in 2013, and fourth-quarter 2013 backlog more than doubled year over year. To keep up with all this demand, 3D Systems is doubling down on its research and development investments. It's also partnering with several companies, including Google, Hasbro, and Hershey, so there's a lot more innovation to come from this Better Buy!

Motley Fool tech analyst Jamal Carnette argues that Facebook (NASDAQ:FB) should move to the next round because of its visionary leader, Mark Zuckerberg. Facebook is succeeding at monetizing mobile and has its eyes on bringing the Internet -- and Facebook -- to the nearly 5 billion people currently without Internet access. If you're looking for a long-term growth story, Jamal says, Facebook is your choice to advance.
