i don't see advantages but issues if you ask something on the SA list 
and finally find out that amavis handles configurations different

ressource usage is mostly the same, amavis is only the glue
the hard work is done anyways by spamassassin and clamav

for both milters exists so you can reject spam instead only flag and 
deliver or even more worse silently discard it - not a real problem with 
postscreen and RBL scroing in front, happy running here since 2014/08 
with zero load even at peaks of 400 junk attempts per minute

smtpd_milters = unix:/run/spamass-milter/spamass-milter.sock, 
unix:/run/clamav-milter/clamav-milter.socket
