We have an experience with CXF and it's predecessor XFire and I can recommend it as solid, quick (WS creating and executing) and reliable framework.
Regarding the issues that you can met with CXF see my post https://stackoverflow.com/questions/289977/recommended-framework-for-java-web-services#290205
And I agree with toolkit, that the biggest difference between frameworks are ideologically: what is the first code (i.e. interface) or contract (i.e. wsdl). See some details here:

- Spring WS Tutorial
- What's New in Spring Web Services 1.5.
