DE Razor shaving can provide med with a BSS shave on a daily basis, even though T rarely shave daily (I like the stubble look) I could do that and get BSS with one of my DE razors, not so with my Fusion. The Fusion could give me a decent shave daily, but not DFS or BSS.
I also like the ritual DE shaving gives me - I know now that one reason I always had fine shaves with my cartridge razors was because I've always used skin products in the shower before the shave, during the shave and especially after the shave.
If you use the exact same products and routines and only factor you changed was going from a DE too a Fusion, 90% would get awesome shaves - maybe not BSS daily, but probably DFS daily.
I just like that you can buy different DE razors and different types of razor blades and use one blade for one DE razor, another for your second DE razor and a third blade for your third DE razor and improve your shaves because of that.
I can still use brush and shaving creams and pre shave cream when I use my Mühle Sophist Fusion, so nothing has changed there, but as said the DE razor gives me an element of extra choice and I like that a lot
The Fusion will never leave my den, but I only use it when I'm in a real hurry and I don't get the same good feeling, when I have shaved with a Fusion as I get when I have shaved with for instance my Feather DE with a Feather blade, my Mühle Sophist R89 De and an Astra SP or my Mühle R41 Grande and a Gillette 7 O'clock Blue SP blade - it's just an entirely different and more satisfying feeling to shave with a DE razor, once you learn the process and adopt the necessary skills
This is why I shave with a DE razor - most of the times now......
And please excuse me, but the guys using the $$$ saving argument for using a DE - take a look at yourself in the mirror, then open your shaving den - so you saved a lot of $$$ by buying all that shaving gear.......don't fool yourself, because you can't fool us with that poor excuse
I have spent literally thousands of $$$ on shaving and male grooming gear since I started using a DE razor. You don't have to, but most of B&B members have a pretty significant budget for shaving gear......just saying..... ;)
