I've seen a 905 in action and it was admittedly the best LED TV I've seen.
I still can't do it, though; and I'd go for the Sammy F8500 before considering an LED TV from any manufacturer.
I know the F8500 isn't perfect. There are minor issues with floating blacks, and occasional brightness pops in 3D. The F8500's MLL isn't quite as impressive as the VT65's, though the F8500 handles 50Hz motion and standard definition content better.
I've seen a calibrated F8500 next to a calibrated 5090, VT65, and ZT65. All produced fantastic pictures. (If you recall, the F8500 won the 2013 Value Electronics Shootout on the public vote, though professional calibrators gave the nod to the VT and ZT.)
I'd love my VT65 if not for the uniformity problems, which admittedly don't notably affect much content. When the issue interferes with viewing, such as during black and white films, however, it genuinely annoys me. The tints are subtle, but they're there.
The other issue is that you can't accurately calibrate a TV when the panel isn't uniform in terms of colour reproduction. (My VT developed these issues after calibration, though the problem is in no way related to the calibration and visible on all picture modes.)
