Perhaps I'm a luddite but...

reliably I can light some tinder-quick tab with a spark-lite - (in the psk)

Some cotton wool with a BSA Hot-spark - (hanging on the keychain)

I never consider myself equipped without a waterproof match safe with some storm-proof matches inside. They work in all conditions and have even been know to be used to light a lighter. - (stuffed in the vest pocket)

Next most reliable is the liquid-fueled lighters (provided you are religious in maintaining the fuel resevoir - (don't have one cause I'm notorious with letting it dry out)

Then the mini-bic - (one in the pants pocket, one in the jacket pocket, one in the vest pocket)

Then the fancy extra bells & whistle high temp super jet lighters - (one in the vest pocket, one in the jacket pocket - the one in the jacket has never worked well but I haven't bothered to throw it out yet - 1 yr and counting).
