What is a better airsoft gas pistol the kind with green gas or the co2 cartridge kind?

honestly as long as it has good reliability, good feel, and fps, it doesn't really matter. the best green gas pistol Ive seen is the blowback green gas luger, silver. exact replica, fps is around 310, or higher. its very cool. look at the reviews.

CO2 is better in some ways and electric is better in it's own ways but CO2 is more accurate and usually is semi-auto but is full auto sometimes. Electric is good because you can recharge the battery.

I'm going to assume that you are talking about co2 and green gas. Co2 is standard liquid/gas, nothing special, green gas is Co2 infused with silicon, which lubes the gun while you shoot so you don't have to clean your gun as often. But both of them are effected by the temperature of their surroundings, in hot weather the fps will go up and in cool weather shooting may break the seal of the mag or the entire gun. There is something called Red Gas (Co2 combined with Nitrogen), but it is illegal in most countries. Red gas also will probably break your gun immediately. Co2 is more common and cheaper than any other gas. Propane is not recommended, however some people use it and it works fine. Hope this helps, Mako Nazarbayev

green gas is more expensive and the guns are more expensive. CO2 is more powerful. I like CO2 more because it last longer than 1 magazine and it shoots harder

I would have to say performance wise C02, but some C02 mags are some times small for the cartridge to fit unless the cartage goes in the mag.
