For the second year in a row, Jones Day landed the top spot in an annual law firm brand survey released Monday by Acritas Research Ltd.

Jones Day unsurprisingly welcomed the news. “We continue to look for ways to differentiate with innovative and meaningful solutions for our clients and are proud that our efforts are memorable,” said Washington, D.C., appellate litigator Glen Nager, the firm's client affairs partner.

Acritas, a law firm marketing consulting organization, based its U.S. Law Firm Brand Index on a survey of 601 respondents who have senior responsibility for buying legal services at organizations with $1 billion or more in revenues. Survey respondents were polled about the law firms' awareness and favorability and asked how likely they would be to choose the firms for top-level litigation, M&A matters, and overall use.

Acritas also compiles an international brand index, and, for the first time this year, has conducted surveys to rank alternative legal service providers. The alternative provider rankings will be released later this week.

In the U.S. law firm survey, Jones Day surpassed Skadden, Arps, Slate, Meagher & Flom as the leading firm last year, and this year it led the rankings by an even wider margin, according to Acritas' findings.

“Jones Day is more favored this year for its practical style of delivery, along with its global coverage and breadth of services—all areas we know align with clients' evolving needs especially now that half of legal departments are assigning responsibility for optimizing legal operations,” Lizzy Duffy, vice president for Acritas U.S., said in a statement.

Following Jones Day and Skadden, in the rankings' third, fourth and fifth spots, respectively, were Latham & Watkins; Sidley Austin; and Baker McKenzie.

The remaining firms, in order of their rankings, are: DLA Piper; Kirkland & Ellis; Morgan, Lewis & Bockius; Hogan Lovells; Wachtell Lipton Rosen & Katz; K&L Gates; Norton Rose Fulbright; McDermott Will & Emery; Ropes & Gray; Weil, Gotshal & Manges; Sullivan & Cromwell; Mayer Brown; King & Spalding; Dentons; and Ogletree, Deakins, Nash, Smoak & Stewart.
