Bi-amping should be on your list of things you don't need or care about since it's a pointless thing to do.
So that leaves good sound (any AVR will get you this), solid construction (not really important given the trend toward digital amps and other eco trends). Up scaling. Unless you can afford a high end AVR you're better off letting your TV or Blu-ray player do it.
Any one of those you have listed would work fine. The Sony BTW gets pretty good professional reviews for sound quality and power output.
