However, this week's surprise faller was the Commission for Racial Equality (CRE), which took the table's second-worst spot.
CRE chair Trevor Phillips's controversial suggestion that black boys should be taught separately caused many media commentators to question the commission's leadership.
Holiday firm MyTravel came third from bottom after it fared poorly in a Holiday Which? customer satisfaction survey.
The Financial Times also reported how the company's creditors were impatient for MyTravel to become profitable.
At the table's summit was Aviva, the insurance giant that owns the Norwich Union brand. Its £1bn acquisition of vehicle recovery group RAC was well received.
Defence firm BAE Systems took third spot after it announced the £2bn agreed takeover of US rival United Defense Industries. The deal would create the world's second-biggest maker of armoured vehicles.
