Mainframe, MVS and zOS Discussion

If we need to compare two files and ICETOOL or SORT both can be used what should be our choice and why?

Does the question even make sense? Is there some comparison presented by sort team somewhere?

IBM's Knowledge Center at https://www-01.ibm.com/support/knowledg ... 00/ice.htm says

Using the ICETOOL utility

ICETOOL is a multipurpose DFSORT utility that uses the capabilities of DFSORT to perform multiple operations on one or more data sets in a single step.
