out of curiosity after a similar thread a few years ago, and being fed up paying for gillette, i bought a silly cheap lord razor to give it a go. less than a fiver with blades i think. i would’nt go back to mach 3.
i’m really lazy, shave in the shower, minimal prep, cheap turkish soap stick and cheap brush, no mirror. its fine. trick is getting the right blade for you. my skin is quite sensitive, feathers/7 oclock rip me up. derbys a bit too dull. sharks are my fave.
i too wondered how a more expensive razor could be better than my cheapie. wife bought me an edwin jagger (about 25quid i think) for xmas and my word its so much better. just more solid, better feel, definitely a better shave.
as i say, no way at all would i go back to mach 3. and besides, all the de stuff, the soaps, the blade packaging etc, are all way cooler.
