[syslog-ng] reliability question (unix-dgram vs unix-stream)

Hi, I'm discussing the differences between unix-stream and unix-dgram on linux with my colleagues. It looks like the kernel-side and glibc-side implementation aren't different in the aspect of reliability. So why is it stated both in the reference guide and in the faq that unix-stream is more reliable?
