For me the .84 GC has been smoother than the Karve w/ C plate.
I'm the opposite. Karve with C plate, which is what I have been shaving with the last five shaves, is smoother, with less blade feel than the .84. That said, the .84 is slightly more efficient.
Same. There is definitely more blade feel on the D. There is a corresponding increase in efficiency, though, so for those looking for a glass smooth shave that last longer, the D is a good option. I love the C, though, as I can shave without fear and there is enough growth that I can shave again the next day.For me, I love the C. I can definitely feel the blade on a D plate. It's absolutely smooth, but I just don't like that blade feeling.
I have all 3 of these razors. I would say the GC .84-P would fit between the Karve SB, C & D plate. The Rockwell in the 5-6 is very smooth because as the Rockwell plates go up in number (increase gap) their blade exposure goes down or negative. I would suggest the Karve SB, D plate and also consider the OC plate in either C or D.GC 0.84-P and Rockwell 6C R5/6 are my two go to razors but I'm really interested in picking up a Karve cb as well I'm just not sure which plate to choose C or D ? I shave every 2/3 days so I need some efficiency but not necessarily over aggressive
