Even for more passive experience, if it were available to you I would say get the X90L from last years Sony line up. Only reason I am upgrading my x900F is it has a known Dolby Vision bug where the hue randomly changes and really ruins the experience.
But, this is why location is important.
As I said above, the only thing that makes me nervous about the Hisense is the reported bugginess of the OS. PQ in our greenroom is not a major concern; The Lady streams crap nonstop and is not concerned with such things. I don't watch sports and game in my room...
For your viewing distance, yo are right at the cusp of 75 or 85" displays. I get the urge to go bigger, but I would hate to give up even just a little PQ for the size.
Frankly this is a personal values thing, just like how much Subwoofer you need (or how many) and what quality Speaker you spend on.
I think if those are your only 2 real options, you gotta decide for yourself. I haven't used one, though as stated have considered the U8 last year, and it's still on my list if I upgrade that room this model year.
I get where the other guys are coming from and agree... but local availability and pricing is a major component of the decision.
