Building a Better Chest Video Inquiry

I love these two moves in this video. Is it ok and effective to use dumbells as opposed to barbells or a smith machine?

Thank you!

Most chest exercise done with BB’s and the Smith can also be mimicked with DB’s. With DB’s there is a greater need for focus for balance, as well as stabilizer muscle activation. I believe that BB, DB’s and machines ALL have a place in training, but if only ONE were an option I would go with DB’s.
