Pretty much? Aren't they anyway? Paint coming at you at 16 bps X 290 fps is the same whether shot out of an Emag, Racegun, Angel, Matrix, etc., single trigger or double trigger, whatever settings. Can you actually tell when someone is shooting at you the difference between whether they're walking the trigger, using a sweet spot, a flat or convex trigger plate, or otherwise? Of course not. This is basically an issue with all electro guns...hell, even Mag RT's were the same way: you can shoot them fast to the point there is little line to be drawn between that and cyclic fire. The whole thing reeks of newbies whining "He's cheating ref! He's shooting full auto!" every time they play against someone shooting anything but a rental gun.
The arguement is crap and the issue should be dropped.
