My favourite shaver is a 5/8 half hollow straight. My favourite safety razor is a Merkur 23c (for now at least) . I don't think I could go with a SE as I love Astra blades with a passion. Unless they make SE Astras and then I'm in trouble .
Well, GEM SE, even as a category including the several GEM varieties, isn't mentioned so I voted other. Straights weren't offered as a choice either. But those fall into "other" so I guess I can vote for both GEM and straight with a single swipe!
My two favorite razors are the Diplomat and the NEW (Bull Mastiff Custom). It's too close a race to call, but I can say this without a doubt that as far as DE's are concerned Gillette's are tops in my book.
