They're all probably very good, but I would personally opt for the Denon 2200, because that's the one I have at the moment
The video is great (no layer pausing or anything) and as far as i can tell, the Audio is excellent as well. I love to sit in my room for long periods of time and listen to DVD Audio etc. now.
I haven't had any experiance with the other models you mentions, so i'm probably commenting out of ignorance, but it seems that many other people like the 2200 also and its also had great reviews, especially for it's price/features/quality ratio, which is all it boils down to in the end anyway.
good luck
let us know what you end up choosing
