Long have I sworn to the Mach3. Trips to discounters blades regularly ended after a few days with rust stains on the cheap blade. The Hydro 5 has converted me: Compared to Mach 3 shaving is just as thoroughly, thereby significantly gentler. The handle is not particularly pretty, but fits comfortably in your hand. The integrated moisturizer leaves a pleasant film on the skin. The donor can be attributed simply fold, is so easy to shave with the reduced blade head of the upper lip area. The blades can be - different from the lattice models of Wilkinson - very clean under running water. A blade lasts me 4 weeks, longer than any other blade that I have used to date. For a while there was the Hydro 5 available for approximately EUR 1.20 / blade. I stay at the Hydro 5, even if I have to buy more for EUR 2.50, for equivalent Gillette products are even more expensive.
