Now, before I'm attacked and labeled a bias, let me just say that this is with my experience and opinion of the big debate of AEG vs GBB. Everyone is entitled to their own opinion. Please, share it below. Just don't be mean about it. I've been playing airsoft for about a good four years. I've come to develop my take on the AEG vs GBB question. The way I see it, many factors have to be put in to really see which is better for which person. First off, are you a speed ball player or straight up milsim? If you are a speed ball kind of guy, you're probably going to go with an AEG for its high FPS. If you are a milsim, you are most likely going to go for a GBB for its kick and realisim. Secondly, what's the price range you're going for? What's your budget? AEGs are mostly a beginner's gun. They are cheaper and can start off in the $20 range (doesn't mean that a $20 gun is practical. I remember my first airsoft gun haha ohhh Dick's the moments we shared). GBB are usually more high end airsoft guns starting around $230 sometimes the weird price of $150. Price is really going to be a huge factor in this. Thirdly, maintenance. GBBs take a lot more maintenance than AEGs. Some people like this, some people don't. GBBs require you to clean your parts, use graphite, gun oil, ect. AEGs don't really need a cleaning like a GBB would. Sure you might have to do a check up on the gearbox and make sure everything is nice and peachy, but GBBs, like real steels, just have a lot of mechanical things that move and need to be check a lot more. Some people have no problem with keeping maintenance and don't find it a chore. Mechanical vs electric. So, let's say hypothetically and not really relevantly, an EMP knocks out all electricity. Well AEGs are out of the question and fried. Not that you'd use an airsoft gun in the case of homeland invasion, but it's safe to say that mechanical is easier to fix and just fix a part than fixing a fried circuit board or having to have knowledge on electronics. I could throw my KWA PTR LM4 (really truly amazing gun I love and suggest highly) into the water and not have any worry what so ever of it shorting out because there aren't any electronics in it at all. If I were to toss my SR7 into the water I'd be a little worried. Yes, a lot of guns are water resistant but there is a 0% chance of something mechanical shorting out. GBB are just more rugged for terrain and nature than an AEG might be. Yes, GBB tend to break a bit more because more things are moving but this goes back up there with the maintenance. All GBB are a bit fragile, but only if you don't give it the proper check up. Those slight battlefield inconveniences are annoying. So let's say you are running around with an AEG and your batteries die. Well you would have to get your spare battery (if you brought one), open up our gun and put in the new one, and reassemble your gun. This could take a while, meaning you might get tagged or worse, lose the game. If you were using a GBB and your gas runs out, you have two options; get your other mag and start shooting again or get your green gas can and fill you may again (again, if you brought it). They both take a little time but for a GBB it's a little bit faster and might save the game. Also I've noticed my AEGs tend to jam more than my GBB. Jamming is pretty bad to happen in a firefight. Unjamming is nerve racking and annoying for everyone. In GBBs however bbs are more prone to breaking inside your gun. Jamming is a thousand times worse than a bb breaking for time wise. Yes, bb breaks can damage your hop up but again it all comes down to maintenance and knowing your gun. Ammo count is another huge factor in this, but it is going to matter what kind of airsoft you play. If you are milsim you probably don't care that you only have 30 rounds in your M4 because it's realistic. If you are a speed ball dude, you probably want to run around with 300 bbs and mow down everyone. In the cold GBBs don't really work. They also don't like to be shot sideways and upside down. With my KWA PTR though, it can do all of that because it's an amazing gun, but other GBBs don't do these things. AEGs don't have those problems so they do well for people that live in colder climate. Now, my personal preference, as you can probably see, I lean towards GBB. I like to feel a bit of kick. I like the realism of having to clean it and really take care of a gun as you should a real steel. I like that there are less serious battlefield problems with it. I like the realism of the ammo count. I like that I can do a lot to it in severe weather and still rely on it. I like that all I have to do is fill or swap mags to get gas and get back in the fight. Since I have a good gun, the shooting sideways and in cold weather problems don't really matter. I hope this helps you decide somewhat on what kind of gun you want. Just thought I'd share what I've seen and feel about GBB vs. AEGs. I've been playing so long, but I just found this app haha.
