I also prefer the forged, milled slide over the stamped/folded one, though I'm aware that some shooters prefer the "balance" of the older ones.
You put "balance" in quotation marks as if you don't believe it. Having owned both I much prefer the stamped slides. If it's in 9mm it's a non-issue in terms of reliability and the balance is noticeable and to me, more so, the weight is less. Now the stainless slides will have better corrosion resistance. But HK, for example, still uses carbon steel slides but treats them for corrosion resistance. It makes a noticeable difference in weight, especially if carrying.
