Solid Stainless Barrel VS non Stainless
 

O.K.
There's been some talk lately about the advantages and dis advantages about having a Solid Stainless Steel Barrel vs a non Stainless Steel Barrel.
I know a Solid SS Barrel is better as it is solid SS vs a non SS Barrel, but dont they (both) have the same chances of becomming rusted and pitted? I know the outside of the SS Barrels look better and hold up better as there not coated or painted or blued, but what if any are the other advantages?
Will the inside of the SS Barrels hold up to more shots and have less wear and last longer?
