Mine are both drop-in kits. I believe DK is the first one that installed allen screws on the trigger itself—for both pre-travel & over-travel. So the break is cleaner. During that time, johnny glock was still using an allen screw in the ejector-housing for the over-travel; and now, he’ll probably do what you request on the trigger. So, the quality/feel would probably the same.
if you really want to see a big-difference; you should compare any of the mentioned trigger kit to a flat trigger.
