I know that these "which razor is better" threads are impossible to answer definitively.

I was wondering how a quality NOS blade, such as a Filarmonica stacks up against one of the newer high end productions, such as a Wacker? I am only using these two as an example because I have heard people say that the Fillys are waaaaay overpriced given their recent popularity but have not heard anyone say that the newer high end razors, such as the Wacker, are overpriced.

Is the quality of the steel and the quality of the shave comparable?
