Red Bic.
I've heard very bad advice from otherwise reputable "survival experts" to go with the cheap, clear lighters instead, "because you can see how much butane is left".
First of all with a Bic, or D'Jeep, or Cricket, you don't need to worry about how much butane is left because they don't leak, and with a little bit of careful back lighting, including sunlight, you can see just fine how much butane is left.
Most importantly, they don't leak, and they don't need adjustment dials to function.
If it's freezing cold and they won't light, rub them between your hands for 15 seconds or so, the friction will heat the butane above its vaporization temp.
They just reliably produce fire.
As a smoker, not proud of it, but as a smoker I can get ignition of a cigarette or tinder bundle with a <1/2 second flash of fire, a full size Bic is a challenge to hang onto long enough to wear out, a mini Bic is only a bit more likely to expire before being lost.
Getting a fire lighted with a Bic vs one of those high temp pocket brazing torches/crack lighters is more a matter of understanding the draft/air flow rather than any ultimate fire lighting reliability. The pocket brazing torches will let you ignite something with no clue about the air flow, but if you want to get a fire stated you need to understand that anyways, and I've got a lot more confidence in the ferocium sparker and wheel than I do in any resistance coil.
Like earlier posters have noted, I have personally sat in a nice spot that I'd sat in years before, and looked down to find a Bic that I'd misplaced a year or two before.
Taking the cover off, catching the freocium flint in my t shirt, and clearing the spring of any debris, maybe oiling it from my hair out the corner of my nose, then carefully reassembling, it's a reliable lighter.
I only buy red Bics, and in the process of training myself to not let them walk off, I discovered that I too was a habitual lighter thief... it's human nature to put the fire maker in your pocket after all.
I cured them both at the same time, I only carry red Bics.
