Shave quality and blade feel. The blade on the GC just feels like a smoother shave. It has more bend on the blade, so I'm not sure it it's that or the more domed cap that makes it feel smoother. The GC with either plate 3 or 4 lasts 12+ hours. It's a different feel than the lupo, a slight notch up in efficiency for me. The GC v2 is better at picking up the stray odd growth pattern spots for me. I would like to try the level 2 plate sometime, but I'm in no hurry due to a lot of reasons including the shipping costs.How are they better for you than your RR Lupo? Which RR Lupo are you comparing out of the 6 options I see?
I'm comparing the GC v2 to the 95 SB and OC. I have the higher plates on the GC it's only fair to compare them to the lupo equivalents.
