I would think that all depends on the species of alien. I would take into account that since Articguana is a reptile of some sort, running out of breath is reasonable. I would assume the only reason we never see this happen to BigChill is beacuse of he Insect like. Insects don't breath the same as Lizards do, that might have something to do with it. So the breathes most likely is a chemical vapor. This would mean there is a chance he could run out, but we dont know how much of the chemical is needed to produce the required effects. Another factor you have to take into is that when Articguana shoots his breathe attack it looks alot more dense and larger in amount. While on the other hand BigChill's breath is not as large in amount and is thinner in composition. So from ive seen, I would say  BigChill would come out on top in this scenario.
