Real world comparisons of Glassfish and JBoss 5?

Question

Does anyone have experiences with both in the real world? How do they compare in terms of performance (memory usage, speed, etc)? Stability?

Does JBoss Seam work well

Answer 1

I started developing a Seam application on JBoss and after a few months tried to get it working on Glassfish. I found the Glassfish enviroment very counterintuitive. I had to fix some strange errors on GF and I could not find any information on the web so after a few days I gave up and went back to JBoss. So personally I would not recommend Glassfish.
