I'm a big fan of the new polymer pistols. They are wonders of modern engineering. Some are even very attractive designs. But moulded plastic will never be as beautiful or have the personality of metal, at least to me.
There is something about the deep blue of an old Colt or S&W revolver, or the time consuming polish on a stainless 1911, or the colors on a case hardened SA sixgun that is just more appealing to me. Cookie Cutter pistols are not a bad thing. I own a few and really enjoy shooting them. But set one next to my Colt Combat Commander and they pale in comparison.
