Scorewatch or a EQ FICO from here will give you the only really useful score available to the general public. However, as a monitoring service, Scorewatch is poor. It really depends on what you want.

If your EQ FICO is 791 and the information on your other reports is similar to EQ, then you don't really need to worry about your score. Anything above a EQ FICO 760 is irrelevant. You will be better served by a service that lets you monitor the INFORMATION on all three reports.
