EdGI is best of the best? LOL
Are you saying this from personal experience or are you just reading random forums? Or maybe you're just judging based on price?
EdGI is very well machined, hop up window is very clean, customer service is great... But its brass. Fucking brass.
Obviously inferior material, bent easily, similar tolerance to PDI - the same if you count significant digits.
