I would much rather use a pistol or any gas/spring gun over an AEG. I find it very hard to just get behind the feel of an AEG because there basicly isn't any feel. AEG's also sound lame. I don't get a rush out of shooting an automatic sewing machine hose. I also have an easier time eye balling shots with any gas or spring gun. The completely realistic action of GBB's is something that cannot even be compared to AEG's in the cool and fun catagories. I despise those players that love to sit there winding away at a completely unrealistic hicap with there AEG. (not that they arn't that hard to take out)
Anyways, you can ONLY take pride in owning GBB's ask they are totally pimp and the pimpness will rub off on to you. Mabey a completely full metal AEG, but you'd have to get it that way out of the box not to be a sucker.
Oh ya and my choices would go GBB, NBB, Spring, AEG
