Ajax Framework for ColdFusion

As always, I am looking to expand my knowledge and understanding in Rich Internet Application development. Lately, I have been researching throughout the ColdFusion and Object Oriented communities for a solid framework that will be a good foundation for me to grow and learn in developing Ajaxian applications in a ColdFusion environment.

The first contender for my needs is JQuery. For reasons based on personality as well as principle, the ColdFusion "sensei" in whom I follow, Ben Nadel, seems to use the JQuery framework and I've adopted a tendency to trust his lead. There are several other options available as well that I have not set aside however. The mootools and prototype sets look rather attractive as well. If there are any JavaScript / Ajax pros out there that are familiar with frameworks for ColdFusion please let me know your thoughts.
