I disagree.  Why do SAP offer user exits, enhancement points etc in standard transactions?  Sometimes a Z transaction is the better option but not always by any means.  If there is a user exit/enhancement point available then looking at that first has a wide range of benefits.
If you copy a transaction into a Z tcode then you are still going to have the same problems when it comes to upgrade etc if you don't perform adequate planning and testing.
