The Gillette Fusion razor blades are very suitable for shaving. The pressure is distributed on the 5 blades and thus a large area that avoids cuts. It's really amazing is if we cut with this system, which has had a beard for a day or a week, the razor is still very effective. I do well three weeks with a set of 5 blades and it is very rare to need ironing 1 2nd time in one place. The 5 blades give no chance to recalcitrant hair. The only negative point is to shave the mustache, then I find the system too large for me. Even using precision blade on the back of five blades, it is not very obvious, in this case, the advantage goes to the Mach3. But I get there anyway, and I think that this system is still good.
