Hi Renee,
Hope you are doing well!
As you have accurately stated, "Question Tags" can be utilized in cross-event reports to analyze responses across multiple events. Conversely, "Question Code" is employed in reporting, as well as in question and answer data tags in emails, if there is a need to retrieve any of that information in emails.
Hope this answers your question.
Thanks,
Shaifali Sharma
