Well, I am going to quote a man unknown, but he knows a **** load about paintball...
"First it was the debate of which is better, automag or cocker? Now, it is the debate of which is better, Angel or cocker?"
I am a big on that cockers are not really more accurate than open bolt guns... I have no proof other than speculation. But I've shot at least 10 angels, and billions of cockers and it seems to me that the cocker is a little more accurate. I can only really notice it when playing speedball and someone is very close to me, and we are both snap shooting at each other. The cocker goes in the EXZACT same place 9.9 times out of 10... then the angel, bushy, imp, etc do not. They are not grossly off center, but just not like a cocker.
