As far as I can work out, DBMS_STATS is purely for
optimizer decisions (presumably thats why they didn't
call it DBMS_ANALYZE).
(If you believe the doco) you can get faster and
better stats with DBMS_STATS (particularly in terms of
partition-wise stats).
I'm using both at the moment, in my case, a weekly
dbms_stats to help the optimiser, and a monthly
analyze to help me (chain rows etc etc).
