George to shorten your post up, your main point is you where trained a certain way and anyone that does things within code but not the same as you is unprofessional and produces shoddy work.
That is your opinion and you are entitled to it, I will continue to use any method that is code compliant.
You show me where the code will not allow any screw to be used to land a grounding conductor (other than a sheet metal screw)
Or show me any evidence that the clamp screw provides a less secure connection and I might begin to care what you think is right or wrong.
