I agree with an early poster on this thread that aggressive razors, as is usually meant, are overrated, as it typically means a bigger blade gap and wider "effective" angle, which is different from an optimum angle. The idea is to remove as much hair but as little skin as possible, but at too steep an angle, more skin is being sloughed off (and often nicked) than necessary, leading to weepers and razor burn. I suspect some guys have more forgiving skin, whereas I have a delightful (ugh) combination of thick whiskers and "thin" skin that is particularly prone to burns and nicks. These big-gap aggressive razors have never been worth the trouble to me. What I've found is that the optimum angle and blade exposure avoids the skin trauma, while a very sharp, rigid blade takes care of mowing through wiry whiskers, no problem. So supposedly "mild" razors like the OneBlade, Feather AS-D2, or later Schick injectors do very well for me and my thick tough whiskers.
Maybe "aggressive" is indeed the right word for many of this big-gapped beasts, since they're prone to bite and chow down on a layer of skin. We should add "effective" or "efficient" to our regular shaving vocabulary to describe razors that are both mild (skin-friendly) but still do their job — cutting whiskers — well.
