This comes up, and I have never had a smoke ruined by the taste of butane, or lighter fluid of any kind. I feel the same way about the sulfur smell of matches being lit. None of them really bother me. If used properly any source of heat will work for me. Heat a metal rod in a fire and hold it over my pipe about half and inch to an inch and gently draw the heat down. A blowtorch works just fine at about an inch and a half. A match at about half an inch. Just DO NOT POINT THE FLAME OF ANY LIGHTER DOWN INTO THE BOWL. It is unnecessary and ruins the inside of the chamber. But, ultimately, it is your pipe, your money, and your habits. Do as you like. :

I like matches. I also like Zippos and Bics. Bics are easier to get a hold of for me, so I usually just keep one in my pocket, but if the mood strikes me, I will fuel up a pipe lighter or put a pack of matches in my pocket. But, the majority of the time it is a Bic.
The weirdest people are those that will light a hemp string and light their pipes with that. Weird may be too strong a term. They just make me laugh. :
