I mean full flaps when you are sure you are going to reach the field where you decided to dich. If you are trying to reach a distant field/runway of course you should keep the aircraft clean in order to increase your gliding distance.
From
skybary.aero:
Configuration - Gear. Gear up is the optimum configuration for ditching.
Configuration - Flap. Most manufacturers recommend the maximum deployment of available slats/flaps is desirable to minimise approach speed. However, judgement is required in this respect since an intermediate flap setting is likely to improve forward visibility and reduce the amount of rotation required to flare in return for some increase in airspeed. Without some or all engines functioning, there may be limited hydraulic power.
