Both TV's buzz but it's very minimal and for certain the Panny buzzes louder. Unless you're living in high altitudes that's the only way you're going to really hear the buzzing to a point that it's annoying.
The F8500 is a reference panel. Other than what's left of the Panny ZT60's there's nothing else in Plasma that can compare.
The Buzz: Overblown perhaps, but I don't think it's a non-issue. I picked up a 60" 3 weeks ago and its buzz is noticeable, compared to that of my older panny GT30 50" in which it is not nearly as noticeable. Everyone's experience is different and unfortunately, sometimes even the same equipment (even the same model) is different too.
The Buzz: Some have mentioned that the it is more noticeable when turning your head and that is exactly what I experience. My guess is that when viewing the screen there is some natural phase cancellation happening and when turning, so the ear is facing the screen, that phase cancellation disappears making the buzz more noticeable.
The Buzz: I've been able to live with it. I have a soundbar w/sub for TV viewing and a 5.1 system for watching flicks. When there is audio, I generally don't hear or notice the buzz. My brain ignores it. I'm usually about 10 feet away from the screen (depending on the recline factor of my Lay-z-boy). I'm planning on putting some audio absorption panels both behind the screen and behind my sitting position and that may help to eliminate some of the Buzz getting to my ears. I'm not doing this to only combat the buzz. My room needs the panels for all audio.
The Buzz: I haven't read everything on the Buzz and one thing I've been looking for is an explanation of what the Buzz is. It sounds electrical, like a static type of sound and not mechanical, like a vibration. What the heck is it (the buzz) and why is it inherent in Plasmas and why more pronounced in some vs others? If someone has a link, link me!
As far as the picture and the features of the 8500, I couldn't be happier. Well, I probably could but I'm unaware of that happiness so ignorance is bliss.
