I bought a Sony 52XBR about 8 months ago. It's personal preference, but I do not like glossy reflective screens. Seems like plasma was especially glossy. I also have a Samsung BD player. I am very impressed by it's ability to upconvert regular DVDs. I have learned the hard way, though, to look for the magic words anamorphic and/or enhanced for widescreen on those DVDs. The only Blu-ray I own is Fools Gold (great movie!). There is a point in the movie, on the yacht, where the camera pans from the bar to the other side of the room. That pan was choppy at 60hz, but almost perfect at 120hz. I'm impressed.
