ICS, generally, has better internals. However, they use a proprietary mechbox design with a chunk of specific parts. There are a few other things about ICS guns that are proprietary as well IIRC. So, in the end, it's a better gun, but more expensive and harder to repair. You could always wait until you're AV'd and get a CA, or one of the others. G&G and ICS aren't the only two on the market. I also recommend that, before you buy, try and get out to a game to check out some other peoples' equipment. Airsofters are more than happy to show off their stuff.
