Or does it come down to personal preference (once you get past the obvious)?
If this has not been covered to death, I appologize for the noise if it has been, can anyone comment.
Too many choices and too much time to find more...
ISF techs argue that 1.3 to 1.5 gain is better for color accuracy, but unless your screen is very small, or you have a 9 inch CRT projector in a very dark room, you have an 80% or 90% chance of greatly preferring the extra brightness and contrast (despite the slight hotspotting) that a high quality non-sparkly 2.1 to 2.5 gain screen offers, like the Draper M2500. If you just have a 7" or 8" CRT projector and a room with white walls, then an M2500 screen will often stand out as being greatly preferable. Even if you have a dark room and a 9" CRT projector, you may still even prefer the M2500.
If you are going to sit under the projector, your viewing angle is probably 15 degrees or less - which is good enough for a Draper M2500.
The M2500 also allows someone to almost double screen surface area and still get the same brightness per square feet as a 1.0 to 1.3 gain screen.
If you're not sure what you prefer - try out a few screens out (expensive), get some screen samples from the manufacturers (Draper, Stewart).
David Bott, of the home theater pictured at www.avsforum.com , tried out four different screens before settling on the Draper M2500.

Rooting for upcoming low-persistence rolling-scan OLEDs too!
I sometimes watch TV with one sixty watt light on. Couldn't do that with a low gain screen!
