Great question! Both MACH3 and Fusion5 have their fans, but if you are unsure which to choose then the following information should help.

MACH3

An enduring tribute to comfort and performance, MACH3 features:

• 3 anti-friction blades for a comfortable, precise shave. The first two blades are Gillette's Low Cutting Force blades -- our sharpest blades. 
• Advanced Microfin Skin Guard helps stretch your skin, and prepares your hair to be cut.
• Lubrication Strip glides to help protect your skin from redness. It gradually fades to white to indicate when to change the cartridge. 
• Premium handle that's perfectly balanced and weighted for a great shaving experience. 

FUSION5

Prefer the very latest shaving technology? Then look no further than our Fusion5 range, featuring:

• 5 anti-friction blades that help reduce pressure per blade, with less feel of shaving irritation than MACH3. The first four blades are Gillette's Low Cutting Force blades -- our sharpest blades.
• Flexball Technology giving total flexibility over facial contours to get virtually every hair (Fusion5 ProGlide & Fusion5 ProShield only).
• Precision Trimmer on the back for accurate edging. Use to trim tricky spots such as sideburns, under the nose, and around facial hair styling.
• Lubrication Strip glides to help protect your skin from redness. It gradually fades to white to indicate when to change the cartridge (all except ProShield). 
• Ergonomic handle gives great control with every shave.

Or upgrade your Fusion experience to Fusion5 ProShield, our most advanced razor, with lubrication before and after the blades for incredible protection, comfort and closeness!

Prefer a Fusion Power razor? Take a look at Fusion5 Power or Fusion5 ProGlide Power. They feature a battery-powered motor inside the handle which generates soothing micropulses to reduce friction and help make the razor glide even more smoothly. 

Once you’ve made your decision, be sure to check out Gillette On Demand, our online service that lets you quickly order blades as a one-time purchase or as a subscription. If it’s your first purchase, you’ll get $3 off -- plus we’ll include a complimentary handle!
