Thanks to @Pippirull for his generous PIF that I won.! I used the same Ozark Mountain shave soap & the same Gillette Tech for each shave to cut down on variables. So, here we go in no special order of the Blades.
7 O'clock Sharp Edge: It was scratchy for me but, gave me a DFS with my medium beard. Not a bad blade at all.
Rapira Swedish Supersteel: It was a little scratchy but, gave me a nice smooth DFS.
Rapira Super Stainless: This blade felt smoother to me & resulted in another DFS.
Sputnnik: Very sharp & smooth resulting in a DFS.
Mystery Blade: Scratchy as heck & not smooth but, gave me a good shave after about 4 passes. @Pippirull said it was a Derby blade with the blade markings removed. My beard started to grow back in about 5 hours. Probably a good beginner blade.
Rapira Stainless Steel: Sharp & smooth resulting in a DFS.
Ladas Blade: Very sharp & smooth resulting in very little neck irritation. I was surprised by this blade & got a DFS from it.
Astra SP Blade: It was scratchy but, still gave me a DFS.
Rubie Blade: Wow, Real sharp & smooth & it really impressed me.! A DFS. Very slight neck irritation with the Rubie Blade.
Voskhod Blade: Another Wow. It was sharp & smooth as the Rubie Blade. Another DFS.! I only got very slight neck irritation from the Voskhod blade as well.
I promised @Pippirull I would do a review on these Blades. The amazing thing is that I did not get one nick from any of these blades at all. I guess Stirling Ozark Mountain is a very nice soap offering cushion & plenty of slickness.
