Be cautious if you are trying them with a straight bar. I always felt a lot of tension in my shoulders, wrist, and elbows due to the inability to move into a more natural position posed by the SB.
I honestly like the DB floor presses best. You can turn your hands slightly for a more natural position and also adjust the DB's so that there is less focus on the shoulders and more on the chest.
A trick I learned was to put a movable flat bench in front of you perpendicular to your body. I would put my DB's on the bench and then scoot under it as if I were going to eat off the bench. Then I could prop my DB's up and "walk" them off the bench to my chest where I'd lean down to the floor and begin my presses. That way you don't end up starting from the floor and sprain a wrist trying to get the heavier weights to your lap.
