What is currently the best third party control set for Silverlight 3? My application will make heavy use of a CRUD datagrid and an interactive global map with my own datapoints layers. I am willing to purchase individual map/datagrid components but would prefer to stick to the one vendor if possible.
My metrics for 'best' are primarily performance and stability.
ComponentOne, Telerik and Infragistics seem to be the big players but there are many smaller companies releasing their own bundles. From my cursory examination it seems ComponentOne have the best mapping control.
What are people experiences here?
