Axis2 has a different internal architecture that allows for better performance. It also supports a newer set of standards (for example, JAX-WS instead of JAX-RPC). Lists of respective feature sets can be found at http://ws.apache.org/axis/java/user-guide.html ("What's in this release?") and http://ws.apache.org/axis2/ ("Features of Axis2 Latest Version").
