I prefer ramped sets myself. Others like straight sets with all the weight they can handle.
But you know what? I've seen some pretty big guys - way bigger than I'll ever be using them to get some more reps in after they've wiped out with heavier weights. They say the drop sets and extra reps made them big.
Since they dwarf me, I'll not argue the point. If you like them and they give you results - then do them. Can't tell you anything about lateral raises because I don't do specific isolation work. I've decided that if I don't have it, I can't shape it so just do compound mass/strength building exercises.
I would say that what works for one muscle or one lift will work for another.
Muscle fibers are basically muscle fibers and should all be trained pretty much the same way.
