I have not tried the dark blue platinum, but my favorite Russian blade is the Gillette rubie platinum plus. These last twice as long as other blades for me and are very smooth.

I was provided with a tuck of this blade when I purchased my Black Mamba from Italian Barber. I never tried the blades until a few weeks ago and I was blown-away by the performance.

The Blacks are great, but I think they are made in India, not Russia. Still excellent blades, maybe my third favorite
