Alright, I know this is probably a broken record at this point but I'm honestly torn between the two TVs. I'm constantly flip-flopping between the E550i-B2 and the M552i-B2. My main concern is video processing, which seems to be the only reason to go with the M-Series over the E-Series in the first place. My setup has everything running through a Denon receiver, and I don't want to constantly play around with my picture settings since I will never change inputs. My concern is highlighted by the CNET review, where the E-Series seems to actually have a higher motion resolution than the M-Series (unless you turn on the motion smoothing effects on, but I'm a little afraid of the "soap opera effect").
Plasma isn't really an option since I sit with a window directly behind me. And it's hard to get a gauge on the picture quality at Best Buy and Sam's Club with their in-store demos, though I was still impressed with both displays so I don't know.
Anyone have any opinions on the matter? Are the local dimming zones found in the M-Series worth it, because in reality that and the refresh rate (which doesn't seem to matter in my case) seems to be the only differences between the two panels? Can someone help break make sense of it all for me? I use to sell TVs for a living and I'm surprised I'm having such a hard time deciding between the two.
