It may or it may not. E-mail 007 to find out if those muzzle velocities are accurate. I don't own either, so I cannot say.
Which is better? You tell ME. Do you want some curious blowback function that doesn't do much, makes your mechbox proprietary, and some parts proprietary, and can potentially fail, but have it look marginally cooler than a normal AEG. Or do you just want a nice bread and butter AEG that shoots and doesn't do that. I would recommend without the blowback, simply because it makes too many parts proprietary, and harder to replace or upgrade, and makes one more system that can potentially fail.
I love freedom and consequently America
