[syslog-ng]syslog-ng vs. msyslog

Hello everybody, I am currently working on setting up a centralized monitoring server.I have been testing syslog-ng and msyslog simultaneously on two servers. I am unable to see much of a difference between their capabilities.Is their some advantage which syslog-ng has over the other available syslog versions? I am sure the experience of other users on the forum can help me decide better. Thanks Christoph Eckart
