There's bad feedback on every TV. Unless the TV is not popular, in which case there are less people to comment on the bad feedback. All sizes of the U7Q should be identical.By the way the tv is available as a 50" as well as the 55" which was the thread with the bad feeback. Is it possible the 50" screen would be any different in reliability/issues. I am clutching a straws here
All comes down to where to make your compromises. Some people may be put off by the fact Hisense use a very basic and buggier smart OS and prefer to go with Samsung instead. But then if you go with Samsung instead you basically get unusable HDR in all titles.
Should think about panel types too. VA panels have more blur than IPS. So they may prefer one panel type over another.
