More surface area for gas exchange. Important for fry when you cannot use filter. I believe that is why they have the different dimension not 100 percent sure.

A "Breeder", typically, is a tank with a 36"x18" footprint. Some of the "breeder" tanks smaller than 30 gallons and larger than 70 gallons will have different footprints.
My 67 gallon "breeder" isnt shallow at all, but is in the 36"x18" footprint, and is technicaly a breeder tank.
i have a 40B and it is a nice tank for starting out, not the biggest one i have but its def got some room for a begginer, just to shallow to do much aquascaping is the only downer
