The arguments are that a bare bottom is easier to claen, but a saubstrated one reduces stress. I personally think less stress will increase growth, and make the fish hardier against any disease.
You won't be surprized I use sustrate. In fact I even use plants and rlittle stones to reduce stress - but when netting the fishk, I start removing them. The plants must therefore be hardy and cheap

It depends on the species and your view on animal welfare. Battery hens produce more eggs.
