It's not about like. It's about empirical knowledge. I have literally logged hundreds, if not into the thousands of hours working with applications built around xp_cmdshell going back to the SQL 7 days. That is not even mentioning DBA solutions. I support an app today that uses ECHO and > to log to a file from T-SQL using xp_cmdshell. What a waste of time.

Anyway, it has been more than enough to learn and experience all the pros and cons of using it. From this I know it's worth steering people away from it. It's simply a shitty tool from a security perspective, an application design perspective, a maintenance perspective, a system stability perspective, from an interface perspective, the list goes on and on.
