Gosh, 4 pages of chest thumping...I know better than you...
FWIW, this is straight out of my B777 FCTM..latest revision..and is identical to the same passage in the 757/767 FCTM.
Flap Setting for Landing
For normal landings, use flaps 25 or flaps 30. When conditions permit, use flaps 30 to minimize landing speed, and landing distance. Flaps 25 provides better noise abatement and reduced flap wear/loads.
Note: Runwaylength and condition must be taken into account when selecting a landing flap position.
