Best Chest Exercises

Do you pause at the top or at the bottom?
I usually do DB on a flat bench or slightly inclined, always use a neutral (parallel) grip, it reinforces the habit of tucking the elbows when benching, then when I press them up I close the dumbbells together towards the inside. Pausing at the top does add a lot of squeeze.

Definitely love for them lol, but I restrict them a bit to since they bug my shoulders. I don’t have much choice of parallel bars in my gym and have yet to find the right hand positioning and angle.
Mind it, they do not HURT my shoulders, they just give me a ton of doms and for 1-2 days after I feel like my shoulders mobility is limited, like the whole shoulder area is tight. I don’t know how to describe it better.
