The SS coated blades you're currently using will be hard to beat. American Safety Razor makes them, along with carbon steel blades marketed under the Treet, Gem Blue Star, and PAL brands. The Treet and Blue Star blades get good reviews; the PAL blades are less loved. Carbon blades are prone to corrosion. I think ASR make an uncoated SS Gem blade too. As far as I know, the only non-ASR SE Blade marketed for shaving is made by Dorco. I've not read any positive comments on the Dorco SE blade.
