Forged aluminum is about 300% stronger than cast (OEM).
I don't know how much the stock rims weigh, but forged is usually about 150% lighter as well.
Plus they look better :P
With casting they melt down the aluminum and pour/inject into a mold.
Forging they heat the aluminum and use thousands and thousands of pounds of force to forge the shape. So because the material is never heated enough to become molten the chemical make up/integrity is much more pure and strong, with far less chance of imperfections. Another thing is under extreme stress (i.e. pothole at 100mph) cast has a greater chance of cracking rather then bending then forged.
If you can afford it, I say go with the forged.
