S-LOL: A lot of exercise go by different name, so I understand the confusion.
With the standing version, you should be using more weight than sitting. Another good delt exercise is See-saw's (alternate) presses, a very affected shoulder builder, which not too many do today.
Cleaning DB's from the floor gives a whole new meaning to intense workouts. Guy's who may have trouble getting a pair of heavy DB's in position, for flat or incline presses, find that including set's of DB cleans (either standing or sitting) solves their problem. For some, cleaning the DB up is their weakest link in doing full service to the flat/incline press. Another benefit of DB cleans is improved forearm/biceps and traps. Good luck.
definitely not the case for me... seated and with a spot I use my stage 3 power blocks for the last set of seated dumbbell shoulder presses (they're like 120lbs each or something)...
standing i don't go over 100lbs... mainly do to the need to balance the weight...
it's funny because it's the opposite with a barbell where i can push press a shitload more than I can military press
