Mini-Bic for me, hands down.

I've been carrying them for 15+ years as EDC.

They are eminently practical and tough. Test fire before you carry: very occasionally (1%?) one will have a valve problem that's obvious right away. Relegate those to wood stove duty.

Alternate uses abound, making them entirely practical EDC:
- church key for top-shelf beer in non-twist-off bottles
- lighting candles in church (this has happened -- fewer smokers these days I guess) or birthday candles
- fuse ends of poly/nylon rope or webbing
- double-flick the flint wheel to light your way through compete darkness without wasting butane; you have to flick twice to make persistence of vision work IME, don't ask me why; not recommended for checking gas in the lawn mower

And: they're small and cheap enough that every jacket/shell/kit has a spare mini-bic tucked into it. Redundancy rules. Surprisingly, they're quite washable as well (whoops).
