The Astra Blue Stainless is a fine blade no doubt, but in my opinion is shaded by the Astra Green Platinum. My experience has been that it isn't as sharp as Astra Green and I can't depend on it to give me a consistent decent shave. With Green I can get a minimum 4 good shaves, with Blue I can't count on 2. Of course depending on your beard and skin, it may be as consistent a performer as Astra Green is for me. Another thing to consider is that Blue is a little more expensive than Green but again, in my opinion falls short of Green's performance.
