We actually did what you describe Jeff, we had a "run off" with Oracle 10G and SQL Server 2005 in a data warehouse conversion test. Both 64-Bit on Itanium (this was a few years ago). Great fun. Go ahead, ask....
Yes, of course SQL Server 2005 won. No, it wasn't that we had gimpy Oracle DBA's either. We had some really good ones (multiples for one production instance too :)).
