I've got 2 Xikars, a punch, a V-cutter, and TONS of guil cutters that I got from various places. My preference is with the Xikar. Never tried scissors though. I'd be curious to see how well they cut.
IMO, the best thing about cigars is the experimentation. Try different gars, cutters, humidors, etc. I've only been smoking for about 1-1/2 years and I'm always learning something new.
