That's a tough choice. The Techs are really different. I am sure color vibrancy is of no issue, SDE hard to tell as you say your sitting 9 to 10' from what size screen? Depending on your eye sight it definitely could be an issue if your in the 120" screen range. Motion handling is another issue as the Epson has FI so if you hate any hint of Soap opera effect LCD really needs it at least at a low setting compared to DLP. The Epson also uses an dynamic iris that some can see pumping to get close to the contrast of the DLP. I don't think brightness is ever an issue as a cheap ND filter can always be used to tame it down if none of the settings can tame it. If your RBE sensitive you really have no choice, LCOS is by far the better choice but you'll need to double your budget for something like a Sony 45es. Epson is also a kind of luck of the draw to see if you get one with good convergence.
