Looking at a screen on the basis of gain only isn't the right way to look at what you're talking about.
You need to take into account other characteristics, like whether the screen is angular reflective or retro reflective - contrast, where your PJ is mounted and so on - gain is just one cog in the wheel
Have a look at some of Tyrg's posts, he does a great job explaining
Good luck
