America's best and worst CEOs revealed: Report

In the '20 Best CEOs' list, which is headed by the legendary Henry Ford, founder of auto maker Ford Motor, Jobs, Gates and Buffett are ranked 7th, 10th and 16th.

The publication, which arrived at the list with the help of a panel of professors of business schools such as MIT Solan School of Management, Tuck School of Business, Wharton School, University of Chicago Booth School of Business, Yale School of Management and Kellogg School of Management, has described Gates as a "cranky and impatient manager - an approach that helped Microsoft earn $60 billion last year."

"He is also known to be somewhat unfriendly to competition. In 2001, to settle a massive antitrust suit brought against Microsoft, Gates agreed to share technical information with other software makers," Conde Nast Portfolio said.

Buffet, the world's second richest man, is called the Oracle of Omaha not for nothing, the publication said. Ignoring the economic downturn and the ongoing global financial crisis, when Buffet bought a stake in Goldman Sachs last year, he received not only better terms than the government, he also got better returns. "As of February, Buffett's $5 billion investment had appreciated 12 percent, while the Treasury's $10 billion stake had fallen 25 percent," it added.

At No.2 in the best CEOs list is J. P. Morgan, founder of financial services major of the same name. Close at his heels is retail giant Wal-Mart founder Sam Walton. At No.4 is car maker General Motors' Alfred Solan while occupying the fifth spot is Lou Gerstner of IBM.
