I think both have great PQ and AQ. I have the tos hd-xa2 that is a great upscaler for SD -DVDS for my sammy dlp. I have a lot of sd-dvds and have no playback problems nor with the hd-dvds. The ps-3 and the bd- players also have great pq/aq. I decided to go with the HD because of the finished specs. I think the bd new specs should be finished!!! around Nov.1. If I were going to get a bd player I think I would wait until then. Anyway enjoy the HD experience. Good luck!!
