Fwiw, we (Tech) had field turf installed two years ago. My opinion is not favorable because when the lights hit it the field looks silver. From the endzones it looks good under the lights (for some reason). Some folks have said it has to do with the size of the blades in our turf and the angle of the lights. I have been on it and would agree that it is probably better for the athletes.
I have also heard thru the grapevine that ours will be replaced under warranty because some of the blades are splitting. Hopefully it will be replaced with the finer blade they are using these days.
