I can’t really say anything on the others you mentioned as I simply do not have them, just the DS-V92 that you see above.
Congrats on your purchase and hopefully it provides you excellent shaves. Do post when you receive and shave with it…
I received my DS C S9 razor yesterday. It took less than two weeks to arrive. It was in cardboard box in bubble wrap plast envelope. I choose it with Destroyer handle. In the box was piece of fabric to keep her shiny. And silicone washer.
I think it is perfect workmanship. Baseplate is shiny from top to bottom. Top cap is mirror polished on top and little rough inside. It looks very much like @GlazedBoker ' s V92 scalloped razor. Only a notch less gap 0,84.
Everything is precise. No wiggle, no aligment problems. Blade sit on the baseplate post so tight that you can turn plate arond and blade does not fall out. But no problem to remove blade.
Destroyer handle is too heavy for me. It has safe grip but knurling could be better. (My zamack AX-SE has handle with better knurling and grip, and they advertise it like stainless.)
Today's head and face shave:
S9 razor
Rubie blade (38)
Bodyshop Maca Root shave cream
Lustray BayRum aftershave
Very good two pass DFS+ shave. I rode the cap, shallow angle as usually. Very little blade feel. Never felt that there was danger for blood or weepers. Even my neck was near DFS.
I never challenge neck BBS . No sting from aftershave.
