Which Airsoft gun is best?

I've heard from people on the Airsoft Ohio forums that the G&G combat machine M4's perform extremely well for their price range (~$160) and have pretty good range and accuracy for the price. If you have a little more money to throw around, I'd suggest a KWA, they're some of the best quality airsoft guns on the market. Echo 1 is also a pretty good brand I have one of their guns and it hasn't failed me yet. . D-Boys are a nice choice if you're starting out and have a budget. The SRC MK36C is a pretty nice gun as well, the wiring inside of it is absolutely genius. It's perfect for cqb games and it's quality is astonishing for its price range.
