Jay,
 I have switched to DBMS_STATS for quite some now. Most databases are 8.1.7.x.
 I have not had any problems running DBMS_STATS. Or from the generated stats.

Now that I finally have all of our databases upgraded to 8.1.7 I am taking some time to look at our method of gathering statistics for CBO. It looks like I should move towards using DBMS_STATS to gather statistics, but I may want to use ANALYZE if I need to gather stats on individual columns (according to Note:166215.1). I was just curious to know if most DBAs are using DBMS_STATS instead of ANALYZE. For the most part, I had been using DBMS_UTILITY.ANALYZE_SCHEMA. I'll probably start using DBMS_STATS.GATHER_SCHEMA_STATS unless somebody convinces me otherwise. Any comments or things that I should watch out for?

Thanks,
