I think it's a collector vs shooter thing.
Last year I began reloading on a progressive press, and went from shooting 2000 rounds a year to about 12,000. My capital is now focused on shooting. Accordingly, the guns I need for this are ones that can be used heavily without major damage to value, and have readily available replacement parts. The new S&W's fit this requirement very well.
I still love the older Smiths, and have not seen more aesthetically pleasing pistols to date. For admiring and casual/occasional shooting, I like my old Smiths. For ~1000 rounds / month of firing, I'll grab a new Smith. I couldn't care any less how the firing pin functions, as long as it does function...and it does.
