CA is better IMO. But it depends i suppose on what you want. A CA might not have as good "performance" ei FPS or RPM, but they are VERY durable. If you want something that will never fail you go with CA, as i did. And don't get caught up in the whole KWA "lipo ready" thing, because they really aren't. It's still very hard on it. Besides, i run a 10.8v battery in my CA with no problems or wear and it gives 20-23ish RPS, which is plenty IMO.
So in short CA
