The Rapira blades are manufactured by Mostochlegmash in Moscow, Russia. Along with Rapira, they also produce Voskhod and Ladas blades. I have not tried either of the blades you have in inventory, but have tried Rapira Platinum Lux and Voskhod. Those two blades are medium sharp and smooth. I have seen review of the Rapira Swedish Supersteel blades that indicate they are neither as sharp, nor as smooth as the RPL and Voskhod blades, but I cannot confirm that from personal experience. I know know very little about the other two blades you mentioned, nor am I familiar with Ladas .
Performance of razor blades depends upon the coarseness of your beard, the sensitivity of your skin, which razor you are using, the quality of your lather and how good your shaving technique may be. Thus, razor blades are highly YMMV. Since you have them in you collection, try them and see how they work for you.
