I love that you can actually make user flows that show interactions between personas. The functionality is easy to use and doesn't overcomplicate things. I have used basically every mapping software out there (I was actually hired to review these tools for a UX team) and I always come back UXpressia as it does what I need from customer journeys right through to Service Blueprinting.
