ULTIMATE reviews may come from users who've experienced different brands, different amounts of blades with the same product.
My cynical ass says a lot of this is just advertising hype.
My hairy ass (and face) goes back to when I was a novice, to a single edge on either side of a single blade. Those fuckers (the razor head more than the blade) were heavier, no matter how skillfully your hand managed things, they dug in more.
These days I've used 2-5 blades, different brands, have no connessoiseur-type reviews, as long as you change whatever blades frequently ... and, don't shave while drunk.
