1) I may be completely off here, but it seems to me that platinum coated blades are generally described as gliding better against the skin and being smoother so shave with. This is also my experience from having tried Derby, Astra SP, Shark SS and Shark SC. But then there is Teflon/PTFE coating as well. Given that YMMV, are they considered to be even smoother than platinum? Voskhod and GSB come to mind.
2) On a side note, what's up with Astra SP at tryablade.com? It's coating is described as stainless, but it should be platinum, right?
