Is black better? I would think this makes the picture appear darker overall. Anyone have a black screen?

The black screens I know need to be projected from behind.
It will give you more contrast and deeper blacks.
It is known for videoprojection in brighter enviroments.
The Black screen material I know is also good for 3D projection, even with polarized 3D.

You also have Black Diamond from Screen Innovation, which is good for brighter ceilings and floors because it rejects the reflections of that corners, but it is a screen that sparkles a lot and personally I don't like the hotspot effect it gives.
The Paralax from Projecta/Da-Lite is better and doesn't have the sparkling effect, but personally I like the HD Progressive 0.6 more if you want contrast.

For work I'm all into videoprojection, and you don't want the Video pixels to interfere with the structure of the screen, because that gives a nasty effect.
I also use HD Progressive 0.6 in brighter situations, but that takes some light away, but gives more contrast back and has lesser problems with reflections, so the picture holds itself longer with some ambient light.
HD Progressive has no structure and for videoprojection that is very important. Also the viewing angle is very wide.
It is develloped by Da-Lite and Joe Kane (a video goeroe) since the videoprojectors are so good nowaday's, that we don't want a compensating screen, but just a very good neutral screen that shows everything as it shoold.
HD Progressive 0.9 was their first and by far the most neutral screen which works beautifully in a dark enviroment.
It's a perfect defuse white and neutral screen, 100% structurefree, color neutral and with a very wide viewing angle.
Strange thing is, that it is just as bright as a normal 1.0 white screen, but it also deepens the black a bit, so you'll end up with a more dynamic picture.

Thank you, Matt. Sounds like I would want to use it strictly for digital projection. How does it work for regular film projection being that the picture from celluloid already has more grain and a somewhat softer image?

With the HD Progressive, there is no other factor that degrees the sharpness and detail of the projected image.
This material is perfect for 4K and 8K projection, but it is already clearly visible with a 2K projector.
But it's a somewhat more expensive screen in the electric version, unless you go for a fixed frame version.
It needs to be TabTensioned for electric and is alowed for sale only in the top class screen versions.
