In today's ­first-round matchup of The Motley Fool Better-Buy Tournament, Realty Income squares off against SunPower 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.

Any company that boldly labels itself "the monthly dividend company," will certainly pique the interest of many investors looking for income, but it turns out Realty Income (O 0.49%) should be considered by all. That it has increased its dividend for 66 consecutive quarters is eye-opening and appealing, but so too is the fact that its ever-important adjusted funds from operations rose by 17% last year. Throw in a diverse revenue stream from a variety of businesses, as well as a great management team, and there is no denying "the monthly dividend company" is your best buy for March.

Solar installation had its best year in the United States in 2013, growing generation capacity by 41%. SunPower (SPWR -2.08%) is uniquely positioned to take advantage of both U.S. residential and utility scale solar growth, in additional to a solid backlog of international projects. Better still, SunPower is the industry leading manufacturer of efficient solar panels, allowing the company to charge a premium its customers are happy to pay. Margins continue to improve in the utility business, and with more manufacturing capacity on its way, Motley Fool analyst Joel South believes SunPower should see exponential growth for years to come.
