I use all of the above. I have tried some back-to-back comparisons of butane v. lighter fluid. I cannot detect a difference in flavor. You can do two things to minimize any potential impact of using a fluid-based lighter: 1) let the flame burn for a second or two before lighting the cigar and 2) use the best lighter fluid you can get, which is usually Zippo brand.
Maybe my taste buds are just not as sophisticated as other folks', but I have no problem using my Zippos with the original inserts, and I have one cigar buddy for whom that is the only way to go. :dunno:
