I don't know anything about these receivers but you should get good performance from both. I've got a Denon receiver and have no major complaints. It is a bit clumsy to use, though. You have to use the on-screen menu for lots of adjustments which is irritating. I'd play around with the controls and see how easy it is to make adjustments.
I'd be wary of relying on subjective comparisions of the units as these don't tend to match up with objective test conclusions. Rip Van Woofer's has a page of useful links linked to on his signature:

I've skimmed through this one:

and the important conclusion is that there was no statistical significance reached when comparing the amps.
Both receivers should have similar performance, but you could check the weight of each. The heavier unit may have a more capable power supply. Also check the specs rigorously, particularly for the DAC or digital output. It should be 0.1 % THD or lower, 100 dB S/N or more, and +/- 1 dB 20 Hz - 20 kHz. If you see any reviews for these units, they might have more detailed spec measurements, which Chris described here:
'Harmonic distortion should be analyzed seperately, not as a total value, unless that total value is known to be a typical spectral distribution. It's important to point this out becuase the THD number can be very low, and distortion can be audible, if it's distributed into unusually high levels into very high harmonics. This will not normally be an issue; but if equipment is defective, or very badly designed(refer to some exotic high-end gear). Also, IMD should be tested at narrow widths, at many individual points at high frequency limitations of the digital system in order to examine technical performance related to the anti-alias filter and the resample system used. Jitter is also of relevance, but will almost always be well under known audibility thresholds. If one really want to nitpick, the clock frequency of a particulare device should be measured if one suspects slight pitch change; as the system could be defective(out of tolerance parts). This should almost never happen, but it's a possibility.'
