It all depends on personal preference. I’ve shaved with many different razors but I seem to always come back to my Mach 3. I love the simplicity of the Mach 3 and I’ve found 3 blades works fine for me. In my opinion, the 5 blades on the Fusion and Proglide makes the blade cartridge a bit too bulky for my taste. I could see how 5 blades might be prefered for someone with a courser beard though. I recently tried a Schick Hydro 3 and it gave me a good shave. It shaved a bit closer than my Mach 3 and it was noticably smoother, but the handle felt cheaply made to me. I’ll use it till my cartridges dull, but I doubt I’ll go by more for it.
