I used a safety razor for the last two years or so. The shave quality is nowhere even close to even a cheap three blade razor. Cheap, but you can get (almost as) cheap and a much better shave with just about any modern alternative.
Funny, I find the shave quality of a safety razor to be far superior to any of the cartridge blades (Like the Gilette Fusion). My shaves are super smooth and close.
However, I still use a my Fusion daily, since it's so fast and efficient. With a safety razor it takes time to lather up and get a proper shave.
I just used my brand new Harry's 4 blade razor, and I gotta say, it just blows away my safety razor, in every category, except it doesn't get the mustache hairs that are really close to my nose, so I used my safety razor to get those.
