I have a PS3 and an XA2. Comparing the two, I think the PS3 is sharper and presents a more pleasing image if only by a hair. I think it has to do with how the Toshiba and the PS3 do their 1080p24. Just my subjective opinion. What isn't subjective is the speed and responsiveness of the players. The PS3 is bar none the fastest, most responsive of the HDM players.
The PS3 will not output HD bitstream, though, for DTS HD MA. In that, the Toshiba will win out. As far as any 1.1 or 1.2 HDMI receivers, you'll find both players equal in decoding to LPCM for TrueHD or DD/DD+.
I've also found that BD's are more reliable because I've never had a problem with a BD playing, but I've had a lot of problems with HD DVD's (all combos).
For this reason, I always choose to go BD when I can just to avoid the possibility of problems and to play it on the ultimately quicker, (arguably) better player.
All my opinion of course.
