The Sony should have a better 1080p image over the BenQ but their are a lot of other considerations to take into account. Just because you can turn out all the lights does not mean your room is fully light controlled. The projector it self is a huge light source and if you have an all white room that light will reflect off the screen and light up the room bouncing off the reflective surfaces back onto the screen washing out the picture. The Sony's big advantage is the LCOS panels as they have better pixel fill and Superior black level over especially DLP. The BenQ's best feature is it will accept a 4K/HDR source and display the full 4K pixels on the screen. If you have no 4K sources and a dark "light controlled" room the Sony is the better projector. With the growing number of 4K sources I would most likely pick the BenQ.
