I'm thinkig about change filter from spamassassin to greylist. Can you compare these two mudules?

Greylisting has nothing to do with spamassassin, and this is not an either/or situation, just like RBLS are not a replacement for spamassassin.

On my system, about 18-20% of the grey listed email eventually gets delivered. Of the 20% that gets delivered, about 50% of that is spamtagged by SpamAssassin. About 80-85% of the connections to the server are rejected outright (RBL, invalid hostname, etc), before greylisting has a chance at the message. If greylisting was in front of our RBL and header checks, it's percentages of ultimately rejected spam would be much higher.
