I bought the 75" U6 6 months ago. Great TV and picture. The Google OS isn't my first choice, but it does have it's good points if you're an Android or Google device user.If you get really critical one thing you’ll notice on a very good TV vs a cheap TV is gradient color banding. Another thing is peak brightness. Cheap sets do a poor job on those two things. There are other things of course. I gave my nephew a 65” Hisense U7H which is a good TV for the money. I think the newest one today is the U7K.
