Snowpulse hands down!! Best on the market
Thats cool they use compressed air. Way better than sending the can away for refilling.
you exchange the cannisters for $50 at any dealer.
One thing to consider is what the airbag is filled with. One of the features that iu really like about the float 30 is that it's filled with compressed air. So in a worst case scenario you get buried and as the bag starts to deflate on it's own it'll release air that you can breathe that can greatly increase your chances of coming out alive, as it gives your buddies more time in there rescue efforts. Just my thoughts.
