Which airsoft should i get?

i would go with the VZ61 CQB Scorpion, it is electric and not gas. the gas guns may be more realistic with the blow back and everything but the gas can be expensive, you lose fps as your gas well empties, the gas is also stored in the magazine on pistols so unless you buy multiple mags you will find yourself constantly refilling it with the gas. also many times after some use you lose a good seal between the mag and the gun itself which will cause it to leak and waste gas. my only concern with the scorpion is the wire stock looks a little flimsy so i would be careful using it. It is electric and has a much larger mag which equals more time firing at your opponent and less time reloading.
