This screen is amazing! I had my projector just projecting on to the wall before the screen came in and it looked good. Once I put this grey 120" screen up, it easily looked 20x better! I have this up in my master bedroom with a 200 lumens ultra short throw projector sitting 32" back from the screen. The borders help to be able to set up the perfect picture and look awesome! The screen definitely gave me a way better picture. Better definition, better color contrast and looks way better with lights on. I went with the grey material because this is now my main tv setup in my room where we do have a floor to ceiling window. With the curtains open during the day, I am still able to clearly and enjoyably watch it. They grey really makes a difference in not letting the picture get washed out with ambient light. Plus it looks great just on the wall when your not watching anything. Installation took me alone a total of 45 min. Instructions can be a bit confusing to read for some, but there are many videos on YouTube that make it easier. This is my first projector screen so I don't really have a basis for comparison, but I am beyond satisfied with this purchase.
Side note: I debated between the white and grey material for a while. I can honestly say that I am happy I went with grey given the amount of ambient lighting in my room. If you will have some light in the room you are putting your screen, I would recommend going grey over white.
