It’s worth it for the dry storage and automatic loading alone. Printing multiple objects one after another on the same bed and same print job, but with different materials is also a great feature and huge time saver for small parts. For actual multi-material prints the best use cases are imo writing into the first layer with a different color or using 2 different non-adhering materials for a thin layer between supports and the part. All of these things require very little filament changes and significantly improve the usage experience.
