So we do not want to get into the discussion about how a CFX tetrahedral mesh is basically just a Fluent polyhedral mesh? Cool, I haven't had to worry about such things in a long time.
But back to the original post, both CFX and Fluent are capable solvers. CFX had traditionally been the "leader" in turbomachinery because it has tools like TurboGrid that simplifies grid creation for such problems. To me, creating a good quality CFX mesh in Fluent meshing seems like adding complexity where it is not needed.
