I survived a lathey foreman
I did not have a lot success with the Bic C.P. the first shave was good and then the blade was unpredictable and so I found them not to my desire.( will revisit) .The Astra S.P are better than Voskhod for sharpness and longevity but for smoothness you could be right.I would put BIC Chrome Platinum and Nacets up in the same category as Feather, at least after the 1st shave. On the other hand, I would put Astra Super Platinum just to the right of Voskhod, but not so far as Derby. But as you say, everyone is different.
