Denon2500Btci vs Panasonic BD 55

[Imdok]

I have a new Denon AVR 4308ci (still in the box). I also bought a Denon 2500

BTCI BD player from Best Buy when it was on sale last week. I have

30 days to return it if I want.

My question is: Is the new Panny BD 55 a better over all player for my use

in HT situations?

I understand the differences between the two (one's a transport only, etc.)

I'm just wondering about PQ and up-scaling.

I bought a Panny BD 35 for the bedroom yesterday and I'm really impressed

with its up-scaling to 1080p of my SD dvds.

Any consensus about which is better technologically, PQ, and up-scaling?

Don't really care too much about the 2.0 version "live" stuff because I'm not

too sure I'd use it.

Thanks
