First choice, when possible, are wooden matches.
Second choice is a quality Old Boy style. IM Corona, Kiribi, or Peterson. Worth the investment. Don't throw good money after bad. Xicar, Colibri, et al are too unreliable. I hear their cigar lighters are good, but The pipe lighters aren't inexpensive enough to qualify as disposable and that's what I've done with most of mine -- disposed of them. I've never owned a knockoff Old Boy, but reports are generally poor.
Third, JetLine flint lighter. Not the best ergonomics, but has been reliable.
The petroleum-fueled lighters like Zippo and Nimrod work GREAT, but mine evaporate their fuel far too fast.
The Linse lighters are a fantastic backup lighter. Small fuel capacity makes them impractical as your primary lighter. I bought a 50-pack and shared them with my pipe club buddies. $1 each.
