Kinda depends on sensitivities. Turn off motion enhancements and there is no soap opera effect but there is some blur. Turn on black frame insertion and the blur is pretty good but there can be some flicker.
Sony is regarded as the best in motion if you use the enhancements.
Coming from plasma I was worried, the motion isnt quite as good no matter the settings. But its also not horrible.
Personally I am really bothered by the soap opera effect, but dont really notice motion blur unless I am specifically looking for it. I also dont notice any flicker with BFI turned on, in store with florescent lighting it was unbearable, at home I notice flicker for about 2-3 seconds after I turn it on in bright areas if I look for it and then my eyes adjust. I generally run the set with BFI on for SDR content and BFI off for HDR, after a few days adjustment from plasma the motion fell off my radar.
