The B7 isn't too bad for glare, it has an anti-glare coating that seems to handle it pretty well. That helps it compete against brighter LED sets in bright rooms. It sounds like the Sonys do handle bright rooms better than the LGs. It also sounds like they handle cable/sat sources slightly better.
I have ATT Uverse which is a little more compressed than other services, and honestly it doesn't look too bad. I can see some artifacts here and there, but it still looks night and day better than the old ISF Calibrated LG 55LH90 (LED 240hz 1080p) im replacing.
