I can't address the specific models you listed in your posting, but I've been running a Pioneer Elite VSX82-TXS (or whatever the heck it's called - you gotta credit most of these companies for their ability to dream up un-rememberable names). Anyhow, I've had nothing but success with my Elite unit. It's big, it's powerful, it cranks, it's full of features that I think I haven't even begun to tap into yet. The only thing I wish it had is HDMI 1.3a, but that's a function of what was available when it came out, not of inadequate design.
Actually, I bought mine as the floor model from a local Hi Fi boutique, and so got it substantially reduced.
I also have a small Onkyo AVR that my boys use for their XBox 360. We've had that for about 8 years, and it's never had a lick of trouble.
I guess that's the beauty of solid state: if it makes it through the first year, pretty much only serious abuse is going to wreck it.
Which puts you back to your initial issue: which model has the features you think you'll use the most? I think if I were doing it over, I might pop for a network adapter so I could plug it into my home network.
Personally, though, I just don't care for the aesthetics of the HK, but that's just me. I'm sure there's a ton of HK fans out there who are willing to testify how little I know about what looks good, so we'll call that a moot point.
Besides, you realize, of course, the risk of drawing any sort of conclusion based on the sample size of a survey of people who respond to this string.
Good luck though. I'm sure any of the models you choose will rock.
