WPF: ObjectDataProvider (with LINQ to XML) or XmlDataProvider---which do you prefer?

Question

I've just read “How to perform WPF Data Binding using LINQ to XML” and this leads me to the question, ObjectDataProvider (with LINQ to XML) or XmlDataProvider---which do you prefer? Should I just fall in love with the XAML-based LINQ to XML approach or are there performance issues here?

This is a snippet from the aforementioned article:

<ObjectDataProvider x:Key="LoadedBooks" ObjectType="{x:Type xlinq:XElement}"  MethodName="Load" >
    <ObjectDataProvider.MethodParameters>
        <system:String>d:\bala\mydata.xml </system:String>
    </ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
