Ultimately, I think I would take the F8500. When all the TVs were displaying Oppo's screen saver (the white Oppo signature moving around the black background), only the F8500 seemed not to have any halo around it. The F8500 has a more than respectable black level, excellent color, and is good with motion. As a sports fan I appreciate that. I would need it in a form factor that's maximum 57" wide, so we're not talking about a 64" screen, though.
