1. You don't suffer the duplication of data (Indexed Views materialize extra data even if it's aggregated).
2. You don't suffer the slowdowns that Indexed Views can cause when doing inserts or updates (I've seen indexed views cripple both)
3. Another advantage is that iTVFs are similar to views except you can pass parameters to them. Think of it as a "parameterized view". It doesn't always work out to be an advantage (Indexed Views can be damned fast because all of the aggregation work has already been done during inserts and updates).
