Review (5/5): let's not compare apples and oranges
Comparing multi-blade razors, Mach III is best: By far the easiest to clean, best balanced, and the most securely attached handle-to-head. These things -matter-, the shaves are otherwise fairly equal. IF YOU MUST: I used double-edge 'safety' razors for years, before there -were- cartridges. If you have a tough hide, or are master barber, fine, but regular guys continue get cut on a regular basis with the old style. Mach III will shave you just as close, you will never get cut.
