I have been shaving with the Rex for about 9 months now and have found my preferred setting is at 2. This works well with both Gillette Nacet and Platinum blades. However, my desire for another razor has returned so I was thinking about getting a Game Changer, probably the 0.68P variant. Has anyone had experience of both of these razors and can give guidance as to how they compare? Also what setting on the Rex did you use?
