I think it is hard to say the "best way." There is a video of a guy lighting a cigar several different ways. I have tried them all such as lighting with matchs while taking puffs and not taking puffs. I have torched them and used soft flames. For me I like a 3 flame torch to get it started than i use a single flame torch to touch it up and or even it out if need be. I will look around and see if i can find the video.
