ehrose,
The LNxxB630 units will also have a matte screen, like the previous model prior.
To determine which would be better is ultimately to you, but our B630 is a really great looking panel. If you have any other questions, please let me know.

I already have the UN55B7000 and love it. I am now looking for a 40 inch LCD for a very well lit room so I need a set that does not reflect ambient light. I was set on the LN-40A630 because it had more of a matt screen than the comparable A650. However the set is near impossible to find now with the release of the B series. Do any of the new B series Samsung LCDs have more of a matt screen that would not reflect alot of light back. I know most of the Sony's would fit the bill but was wondering if any of the 2009 releases would be as good as the Sony's in this department
