I wouldn't say that one is better than the other. For instance, I tend to choose Storyline 360 for projects where I have more time to create a really custom experience that needs to work on every device.
But in this example, I chose Rise because I wanted to build a compliance course in a few hours that would work on every device—but I didn't want to invest a ton of time and effort into creating a complex branching scenario. I felt like I could make the important points effectively through a simple scenario with robust feedback.
In short, both are authoring tools. Both allow you to create multi-device e-learning. Storyline 360 is great when you want to create something custom and/or highly interactive. Rise is a good option when you don't have as much time or just don't need to create something custom or highly interactive. Hope that helps, Andrea!
