I have a brass one, and while it doesn't "kill" the shower pressure, it does reduce pressure throughout the system, I guess, doing what it's intended to do.....
I would think if the water connection at the CG was not potentially too high for the plastic piping and pipe clamps, you wouldn't notice a difference with or without it.
So I will continue to use mine.
