I'm wondering which of the three kinds of Gillette two-blade cartridges -- Trac II/GII, Atra/Contour, or Sensor -- is the mildest, in your opinion. I'm not looking for which one is the 'most DE-like' (that would be the Trac II/GII, due to its fixed head) or the 'best', I'm only interested in the relative aggressiveness of these cartridges. Thanks for your replies!
PS Trac II and GII are identical; GII is the European name. Atra and Contour are identical; Contour is the European name.
