I've not auditioned the other receivers you mention, but I do have a Panasonic XR-55 that I've been using. I'm using it back and forth with a Denon AVR-3200, which though old was just one or two models below Denon's flagship model when it came out. I have to admit that it sounds remarkable for it's price. I've not owned anything made by Panasonic before that I'd consider even mid-fi, but I'm really impressed with this little receiver. I don't do any video switching with it, so I can't comment on that. All I can say is IMHO it just sounds way better than the $1200 (in 1998) Denon. For $229 or so it's worth a shot.
