the Onkyo 905 (and 875, for that matter), has a better upscaling chip than the Denon, but... Onkyo buyer beware! There are supposedly audio / lip synch issues with the Onkyo line that could be more annoying than it's worth.
I had no big issue with the Onkyo lip synch, but this is probably a function of the TV, the actual setup (HDMI? Component? Optical?), and the source material.
However, the Onkyo may be more picky than most as far as interoperability. Clearly had a problem with broken packets in DirecTV's Dolby Digital where the Denon did not.
"I was following the whole firmware update in the 805 thread when it became available through unofficial sources. The consensus was that it did nothing to help the lip sync issue. So I never bothered. Email from Onkyo confirmed it's hardware related, too many DSP's in the signal path and each one adds it's own delay. Unfortunately no firmware update could ever fix that. If you've really got your heart set on the 875 then buy it where you can exchange it for the 3808 if things go awry."
I don't know if this is true or not, as I didn't follow the firmware thread that closely.

I don't know about the Sony.

Known issue with the DSPs in the Onkyo which is remedied via a firmware update.

I was under the impression that the firmware updates could not fix the delay, as it's based on the speed of the processing chips.
