I haven't tried shark super stainless, so I can't say. Blades are very ymmv items anyway.
I'd strongly recommend you give each of the Gillette 7 o'clocks and silver blues a try. Awesome blades and well priced. Try the Israeli personnas, both the red pack and the crystals. I don't like the Reds, but others do. Try feathers because everyone should at least once. I like Treets, but they are not a popular blade. Polsilvers are outstanding, but not cheap. Astras are a great value. The only blade the Maggards offers that I'd avoid is Kai. They are super expensive, and I don't think they are as good as any of the above blades.
