EY-Parthenon vs. Oliver Wyman vs. ZS Associates?

Hello!

I have offers from EY-Parthenon, Oliver Wyman, and ZS Associates (San Francisco, CA offices). This is for post MBA level senior consultant/associate roles (I am graduating my dual MBA/MS degree in Spring 2022). The EY-Parthenon role is generalist, while the Oliver Wyman consultant role is specific for healthcare and life sciences. ZS Associates is also generalist, although I have heard that about 75% of their clients are life science/med device companies. My background is in the life sciences, and I am getting an MS in biotechnology alongside my MBA.

What are your thoughts on these firms? Which one(s) are best known in the consulting industry?Which firms are best for life science strategy projects? Does any one firm have higher placement into MBB later down the line?

Thanks!
