If you shave with a sharp double edge safety you are at 95% of whatever the "4 blade megarazors" do. The only ones I might like a little better are the bendy heads that conform to the face a bit better. But it's not worth destroying the environment or paying 20X as much for the blades.
They make em bendy now? Hmm... back in DE land, the state of the art is holding the blade extremely rigidly with the clamp much closer to the edge. Think a woodworking planer rather than someone holding a floppy knife. Henson Shaving. Very good reviews on the site even in comparison to other DE razors, similar from people I know. https://hensonshaving.com/
