I started with safety razor like your husband, moved to a straight edge, then finally the three blade form i use now. I find the one i have now is the closest and thr quickest. Since i do my scalp where its hard to see and awkward the straight edge was quite slow and woukd take 3x more passes than the tazor i now use.
That said for a beard a straight edge can work quite well.
