I've owned and used all three of these razors, but only used PTFE blades. I then bought an Ever Ready Streamline and sold all three. Massive difference for me in smoothness, comfort, and closeness/post shave feel from the ER - while just as aggressive as the Clog Pruf (maybe more so) which to me is more aggressive than the MMOC. The G-Bar, is just too tame.
Now I want to try the stainless and carbon blades.
