EU,I would have to agree with Anon. I used to work for EY in Eastern Europe, where KPMG was viewed as the last of the Big 4. Generally, based on my research of the Big 4, I think the ranking is the following: PWC, EY, Deloitte, and KPMG. However, it is important to reasearch them based on particular industries and the markets they are in. PWC may be leading in one country or region, but then Deloitte or KPMG may be the leader in another country. Check out Hoovers database, draw a strategic map of these companies, see which one has what you are looking for.Best,Olga
