Agree with David that you may better run your own benchmarks and decide by yourself which one is better. Asking around  here, most probably everybody will say Geronimo..
A god starting point would be this survey carried on by Evan Data Corporation, where Geronimo won over Weblogic, Glassfish abd Jboss

or (might be not 100% accureate)

this one here (which strangely doesn't show Geronimo as an option)

Here you have a guide to choosing the right J2EE AS for you



BTW : Geronimo is my choice =P

Hi Can any one help me in comparing Geronimo (Axis 2 and CXF) with Sun
Glassfish and let me know which of them is better in terms of performance
and functionality.

By selective tuning and creative benchmarketing you can make any app server look ideal.   Both app servers work fine.  Here, we tend to think Geronimo is more flexible and extensible.  You really need to investigate for yourself.
