My Experian credit score was 720 and it listed it in the "good" category. My Equifax was 670 and also listed as "good". But I guess I won't have to worry about the Experian one anymore.
I never put much stock in that categorization as it is subjective anyway. In practice it may not make that much of a difference and all depends on the lender/creditor anyway. myFICO's intrepertation is only a visual guide not absolute. IMO.
