I EDC a BSA HotSpark - ever since I saw Tom Hanks in that shipwreck movie (name escapes me at the moment - old age!).

When in the field I ALWAYS carry a refillable butane lighter, a magfire sparker, a bag of Vaseline-covered cotton balls, and some kind of matches. The lighter is my primary means of lighting fire while camping.

When out with the Scouts - always relatively local - I carry strike-anywhere matches in one of those cheap orange plastic waterproof (?) match cases. These are mostly used to light my Coleman fuel lantern (the only decent way to light it I've found).

When out in more extreme regions (Glacier National Park most recently) I carry a K&M aluminum waterproof matchcase with REI waterproof matches and a striker pad. I do light one off every once in a while to make sure they are still functional.
