There has been numerous excellent threads on this topic, some of which I have referenced at the base of this post, and I would like to acknowledge and thank previous contributors.

There are subtle advertising and packaging variants of the above; examples include:
From my own blade stash, here are examples of the four variants:
I have shaved with all the above blades. In my personal experience, they are all excellent performers. In terms of longevity, I have shaved with individual Tungsten Steel and Tungsten Plus blades for 20+ shaves, and changed out not for performance reasons, but because I wanted to try another blade. I have shaved with the Super Platinum Chrome (SPC) blades for 10+ shaves, and again changed out not for performance reasons, but because I wanted to try another blade. I would need to do a specific trial with the SPC blades to see if they stretch out to the same longevity of the other variants.
In terms of my experience with regard to performance, the Tungsten Steel and Tungsten Plus blades feel identical - smooth, sharp and both have extraordinary longevity. In my experience, the SPC blade is as sharp as the Tungsten Steel and Tungsten Plus variants, but is even smoother.
If members wish to inquire on the metallurgy and coating of these blades, I am happy to discuss via PM. I am a tertiary-qualified professional metallurgist with 30 years industry experience.
