Seems to me I read somewhere that propane is the less landfill friendly option, because the small, disposable cylinders cannot be refilled and are disposed after one use (although I also heard they are working on recyclable cylinders now).
But for me, there is just something satisfying about using the old-school white gas lanterns and stoves, with the pumps and fuel tanks, knobs and levers. I finally sold my propane lantern, and I've got all white gas equipment now. So my vote wholeheartedly goes to white gas.
