I own a couple punches that I use pretty much whenever the cigar allows me. I have a double blade but between it being cheap and my probably lack of cutting skill, the punch is just easier. Beyond that, I can't really explain it but I just prefer to smoke them that way.
Oh, and those scissors bother me because they have two blades facing one direction and one the other...it's not symmetrical. I doubt it would actually hinder them from cutting efectively, but I guess I'm kinda OCD that way :S
