According to the blade gap chart the black tip has a larger gap and therefore probably more aggressive. That said agressiveness is very subject and in reality the two are probably close enough together that you wouldn't feel much of a difference.

Hmmm.....the way I read the chart was that it was a "black handle" not a "black tip". Maybe I got it wrong.
I say that because I have a 1951 blade tip SuperSpeed with the aluminum handle and was wondering about the comparison.
Thanks.
As mentioned, I have an aluminum handled black tip that works pretty well. Very mild but very comfortable shaver. I was just wondering which was more aggressive, the black tip or blue tip.
Thanks for all the replies. Now to make up my fickeled mind.
+1...The Aluminum I under stand feels a little milder because of its lighter weight......
Why put yourself through all that thinking and difficult choice making?
You need both!
(It'll happen sooner or later anyway)
