Try it out and find out, is the best answer I can give ya. For me, DB pressing serves a few specific purposes: one is to train stabilizers. I used to feel like I wasnt in control of a barbell with more than 3 plates, once I got up to reps with 100+ DBs that problem went away. Second is to isolate the chest a little more, take out the triceps some. Third is convenience, its nice to superset DB press and DB rows with the same weights sometimes.
Im not sure if you can work DBs to fix that sticking point you were talking about, but maybe.
