Which Henson? It comes in 3 "levels": + (mild), ++ (medium), and +++ ("aggressive"). It also comes in aluminum or titanium. As for the Razorock, I am assuming you refer to their stainless steel Game Changer razor with the .76 baseplate. Are you considering only these two razors? What other razors have you used and with what results?
Any particular reasons why only those two? I ask because I didn't really get along with either the Hensons or the Game Changer. What other razors have you tried?
To answer my own question the Henson ++ is way better. The Best razor I have tried in 10 years of shaving.
If you mean RR Game Changer .76, I own it and the Henson. But I use only one, the GC. I’ve had the SB plates below and above the .76, and also an OC. This particular one is my sweet spot. It’s currently matched up with a Timeless Ti Crown handle. I don’t appreciate the very narrow built-in angle the Henson wants me to use. It’s not intuitive for me as the Game Changer is. For me, the GC shaves me better, i.e., closer and easier, with less attention to maintaining the right angle, than does the Henson. I prefer the look and feel of the GC. When doing a side by side, in my mind the Henson is a toy, the GC is a useful tool.
