I have one of my Great Grand Mother's 10" Skillets.  From what I was told, it was used daily, for many of the meals.  It DOES sear better than any of the Lodge I have.  I am not sure if it is because of how it is made, but the damn thing looks like a sheet of glass inside.  The constant greasing, heating and cooling have made one of the best non-stick cooking surfaces I own.  Eggs come out PERFECT!   
I am sure you could get a new Lodge up to the same level, but that will take years.
