Any advantages or disadvantages depend entirely on how the SMS constructs are built and how they are administered. Purely site specific.

The only real problem that I encountered with DATACLAS was when the RECFM and LRECL were specified in the DATACLAS and the file was not opened for output it had an invalid DSORG, but I believe this is no longer a problem now as a default DSORG can be applied.
