I visited comet for the second time to see the pioneer 436 in action.Luckily it was placed right next to the panasonic pv500. the feed was hd with various scenes including sky diving, underwater scenes and football. The black level was not in the same league as the panasonic in my view. The pioneer had a strange mesh grille [gauze] effect on most images. depth and detail of the image was better on the the pv500 with rich colours and slightly better shadow detail in most scenes. Motion on most scenes seemed to have jagged edges artificial look to them especially the players on the football pitch. colour banding was evident in the shots of the sky but slightly less than the panasonic. I think this is an incurable problem for plasma. Overall I would choose the panasonic over the new pioneer due to better motion , black level and general richness and smoothness of the image. I just coudn't ignore the mesh effect on the pioneer screen.
