Well i have a cocker myself. What is obvious is that the cocker shoots straighter, and electros (angel, matrix) shoot faster. I don't know how much $ you want to spend, but for the price of an Angel you can get a very awesome custom-autococker. In my opinion the ultimate marker is an autococker with an electronic gripframe. Then you'll have the accuracy of a pump-gun and the ROF of an electro. -But still a WGP autococker is great out of the box. Throw a new barrel and a new gripframe on it and you're very much ready to rock. On the custom cocker scene theres comming more all the time, and cockers are still some of the bestselling markers! Another thing is that i like to see that something is happening when you shoot the marker, and looking at all the chrome stuff jumping around is well cool. I'd go with the cocker!
