I prefer AC style SE razors. If you've used shavettes, you're already familiar with the blades. I find I get a smoother 2 pass shave with an AC SE razor, with Colonial razors my weapon of choice. The blade is thicker and stiffer and does not bend in the razor like a DE blade. Perhaps that's why they seem to work better for me? I've never tried a 1/2 DE razor.
