In today's ­second-round match-up of The Motley Fool's Better-Buy Tournament, Silver Wheaton squares off against Bristol-Myers Squibb 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.

Motley Fool energy analyst Taylor Muckerman thinks Silver Wheaton (NYSE:SLW) should move on to the next round because of its unique business model and low cost structure. Working in tandem with the biggest miners in the world, Silver Wheaton acquires its silver at around $4 per ounce while the metal currently trades just above $20. With mines in secure geographies, Silver Wheaton is an excellent way to invest in both silver and gold.

Bristol-Myers Squibb (NYSE:BMY) trades at a premium price, but investors get premium execution in return from this best in class operator, argues Motley Fool analyst David Williamson. Bristol set off the immune-oncology race thanks to strong results for nivolumab, and Bristol remains in pole position. Peak sales estimates put this drug among the best of all time. This isn't a company afraid to make bold moves via a big acquisition or divestment, recently washing its hands of its large diabetes partnership and ceasing certain development programs to focus on more profitable treatment areas in its pipeline. Bristol has a 2.8% yield and is expected to average 14% growth over the next five years -- a rare combination in any market.
