forged is stronger than cast, materials being the same- IN ANY PART- no matter what you're making- to make a casting as strong as a forging, the casting must be much thicker/bigger- basic engineering rule of thumb, to make something stronger, make it out of better material, or make it bigger.
Ruger basically used the best materials, but cast them to save time/money. Those same materials in forged would be even stronger.
Uberti went to forged frames- they are superior to cast frames. In the past, they were using castings.
