As I typically don't smoke indoors (unlness at a tobacconist), I find the Zippo to work pretty well. I'm not a fan of the fluid, even if it is "low odor" these days, but wind is a tough one to deal with. There's butane drop-in inserts for Zippos that have their fans and their critics, too.
Butane lighters are fine, too, so long as you are enjoying your smoke. If you're sucking butane and not getting the pipe lit, it can really be frustrating--though they usually light pretty reliably. I like butane lighters that are angled that can shoot down into the bowl, this helps immensely, and can even work pretty good while in the wind.
On the Bic subject, they're cheap, reliable, and you won't kick yourself for losing one (check the prices of Old Boy and Dunhill lighters--losing one of those would hurt, both because they're great lighters and rather expensive). Plenty of guys use Bics, I keep one as a standby. I find the Bic Mini to be easy to handle and manage with a pipe.
Matches are great, they work well when indoors, and have a wide flame to really get the pipe going easily, I just find them awkward to use when working in the field and being outside, so I don't use them.
Lighters are kind of a pain in general because they can eat you alive spending $10 - $20 at a time finding the right one, and I've often bitched and moaned at how a $1.00 disposable Bic is a great lighter, but a lot of the more expensive lighters don't offer the same reliability.
Find what works for you and gives you the best smoke. 8)
