I just visited comet to view the Pioneer 436 xde in B'ham. The pioneer 435 xde was placed next to it. The black level to me looked almost identical to the old model. Despite the black being the same the picture on the 436 xde had much cleaner processing [it may have been a freeview feed, not sure] not much blocking evident. nice bright colours but strange greenish greys and fairly dull whites even when I turned up the contrast above 50% mark. Did not notice hardly any false contouring/banding on the pioneer but very slight banding was seen on the Panasonic 42pe50 and pv500. The panasonic 42pe50 I saw had deeper blacks, whiter whites and natural colours but picture was quite a bit noisier [probably crap feed]. I think I need to test these screens with some dvds next time I get a chance. I would definitely go for the panasonic on white and black level but whats in between is also important. not sure what to buy!
