In the spirit of World Cup competition, we're holding our own tournament in search of the Better Stock Today. We're pitting 32 companies against each other, and you, the reader, will determine the winner.

Today it's the quarter-final stage, and LINN Energy takes on Isis Pharmaceuticals in our search for the better stock.

Bracket showing companies that advanced from the group stages.

Joel South, energy analyst at The Motley Fool, thinks LINN Energy (NASDAQOTH:LINEQ) is the premier upstream MLP and worthy of your investment. LINN offers a top-tier distribution yield of 9.7% and management continues to execute on its strategy of acquiring mature oil and gas assets that are operated strategically to increase cash flow and return excess cash to unitholders. 

David Williamson, Motley Fool health-care analyst, thinks Isis Pharmaceuticals (NASDAQ:IONS) should advance to the next round because of one big reason -- its amazing drug pipeline. Wall Street heralds it as the best in biotech and puts Isis in play as a takeover target. A virtual who's who of Big Pharma members have struck partnership deals with Isis. The company already has orphan drug Kynamro on the market, and it has also seen recent success from a midstage study for an anti-clotting drug. A recent sell-off has given investors a chance to get this deep pipeline at a discounted price.
