I went on a 2 month semester at sea, there was no barbell, only DBs going up to a hundo.
Take my word, by the end of sea term I could hit 100's for 10 for two sets. When I went back to normal benching after 2 months of DBs I had the most controlled, strict, bench press in my life. The bar moved in a perfectly straight line at a constant speed. It felt strange having so much control, it was like I was using pure muscle to push the bar up, rather than firing it off my chest so to speak. Now its back to firing it off the chest, so I am incorporating DBs again and seeing if I can go back to the more stabilized form I had after sea term.
These to exercise definitely correlate to an extent.
