SpamAssassin or Rspamd? Recommended settings?

Hello all,
i'm kind of desperate because my servers are overwhelmed with incoming spam, and the default settings of SpamAssassin in Directadmin are basically useless..
So, i figured i'd ask for help here..
First of all, which is better: SpamAssassin or Rspamd?
Second, are there Recommended settings for either one beyond the default Directadmin settings?
For example, i've added the preference in the user_prefs, but it makes no appreciable difference:
score RDNS_NONE 3.0
Also, i get the feeling that SpamAssassin is not checking RBLs, not that RBLs are very useful in the age of AWS..
Any help on this matter would be greatly appreciated!
EDIT: my servers are CentOS+Exim
