Adobe recommends using eVars, not props
From the props documentation page:
Adobe recommends using eVars in most cases. In previous versions of Adobe Analytics, props and eVars had advantages and disadvantages to each other. However, Adobe has improved eVars to where they fulfill almost all use cases for props.
This one puzzles me. eVars work with events because eVars persist, while props don't perisst. For instance, when building hit-based segments for traffic reports, I would use props because I know I won't include unwanted hits due to an eVar still being set.
What are your thoughts on this recommendation? Do I use an out-dated understanding of how eVars and props work?
