In a sign of a legal market where competition for work is stiffer than ever, a survey of legal buyers’ preferred Big Law brands has a new No. 1 for the first time in its six-year history.

Jones Day topped the Acritas U.S. Law Firm Brand Index, released Monday, after finishing in second place for the previous five years to the same firm: Skadden, Arps, Slate, Meagher & Flom. This year, Skadden ranked second and the top five was rounded out, in order, by the newly re-branded Baker McKenzie, Latham & Watkins and DLA Piper.
