Matches depending on your variant may or may not work in extreme environments. Such as strike anywhere matches. In foul weather they are fairly useless. I do waterproof mine with a thin layer of clear nail polish, but again that only solves the problem of them getting wet. I also suggest keeping all matches in a waterproof container. Most waterproofing containers also have a flint glued to the bottom for a back-up fire starter.

I can only fit 20 strike anywhere matches/15 UCO wind/waterproof matches in each container. That is only 35 fires(in two containers). For the same amount of space a Bic averages 3000 lights. You will hear guys say that "disposable lighters get wet and wont work". So will most matches, and that's why we place them in waterproof containers. A Bic will also strike 10 for 10 whereas cheaper lighters won't and I've never had a Bic fail me.
2 Match containers =35 fires
2 Bic Lighters=6000 fires
I believe that answers the question. Bic Lighters kill matches in a survival scenario. I'm a big proponent of having 3 methods of fire. So I do carry matches and Bic's. But if I had to choose just one. I'd go with the Bic.
