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.

Gilead Sciences (NASDAQ:GILD) takes on Seadrill (NYSE:SDRL) for this first round-robin match up in our search for the better stock today.

Motley Fool health care analyst David Williamson makes the case for Gilead to win this match up. He believes Gilead's Sovaldi will continue to beat analyst estimates and that its runaway success will continue. Estimated to do $1.4 billion in 1st quarter sales, the instant blockbuster clocked in at $2.3 billion. Gilead already has an even better combo treatment in the works and despite its high price tag, Gilead's future rivals don't appear willing to undercut its cost. With an estimated 150 million hepatitis-c cases worldwide, curing the disease will prove beneficial to humanity and Gilead shareholders.

Joel South, energy analyst at The Motley Fool, thinks Seadrill is more than worthy of your consideration today. Successful investors have been building significant wealth for years by finding solid, high dividend paying stocks. Seadrill sports an industry leading 10% yield and with solid contract coverage and a fleet of new drilling rigs, investors can count on Seadrill to be among the best offshore drillers in the world.
