Verdict is on the common 47/48 - 53 Aristocrat which is the one on the right in that photo. Those 2 are distinctly different razors as it turns out. The 47/48 - 53 is a lot more aggressive, you can feel it right away in the blade feel on the face and at the end of shave with how much burn the vinegar splash gave me compared to the other razors. So as it turns out the change it handle styles is where the aggressiveness of these razors significantly changes not the head style. Same as when the Aristocrat transitions into the Diplomat product line in 53, change in handle style corresponds with a more aggressive razor than the prior version. So the final results are the common 46 - 47 is still the best overall shave and closest for me anyways out of all 5. Number 2 and 2a would be the 1st 47 variant and the common 47/48 - 53 variant. The shaves are too similar for me to call one over the other for the end result. They differ in how aggressive including irritation during and after the shave. I guess it would be a personal preference what type or razor you like to use here. Number 3 the 2nd 47 variant. It is close but no cigar. Number 4 is 40/41 Regent Tech/Aristocrat, easy shave but clearly removes the least amount of overall hair for me.
