Balanced field length is when no account is taken for any clearway, but you can account for stopway.
This means that TODA can't be any longer than ASDA.
So ASDA=TODA. This is the defintion of a 'balanced field'.
Your 'AGD' will be equal to your TODA if you are field length limited, or using a reduced thrust takeoff to achieve the same effect. So in some circumstances your two options are the same thing.
