How do we decide whether to use SYNCSORT or DFSORT . ? Do we have a choice

Your site chooses which product (DFSORT or Syncsort) to license and install, so that's the one you use. Generally each site only has one of the products. However, some sites have both products available. In that case, one product is installed as the primary product and would be invoked automatically. The other product can only be invoked by using a JOBLIB or STEPLIB with the libraries where the product was installed (your System Programmer would be able to tell you if both products are installed and what libraries to use to get to the secondary product).
