I'll go along with the crowd - try several until you find what works for you. Here is what I have settled on.

1) Refillable butane lighter (carried and spare in BOB) - I have good luck with Colibri Brand
2) Mini Bic in a C2 case (in all cars and small kits) - stores a long time w/no accidental button pushing

3) Strike anywhere matches (in all BOBs and small kits) -Keep in a water proof container
4) Sparklite (in all BOBs and small kits)

Tinder always makes lighting a fire easier so figure out something that works for you and is easily carried.
