for Germany Simon-Kucher & Partners is the go-to address for marketing, sales and pricing! They have been identified by numerous business journals (e.g. brand eins, managermagazin) as hidden champion - although the consultancy is not as "hidden" anymore.
You can find some impresion of there ranking here:
