Let's see, on a normal 25 flaps landing they require more runway to stop because of the faster speed. Advantages to 25 (less flaps)? More likely to hit tail skid, less fuel use, less noise, better initial go-around performance, if engine quits on short final better performance (now we can start all the what ifs).
The advantage to more flaps is always a slower airspeed and less kinetic energy to dissipate during roll-out and a lower body angle and view during low visibility approaches (but we don't teach that any due to auto-land).
We get paid to read, practice and apply what we are taught by the FM, FOM and the manufacturer's directions. And yes we are culpable for our decisions, it's what we do.
