I haven't bought a TV in a couple years but I've been partial to LG because they often use IPS panels and not MVA, PVA, SMVA, TNs etc. That doesn't' always make a difference with low-res chores like TV, games etc but it makes a difference with photos. I won't get another TV until the 4K scene settles (coming on strong hardware wise but content isn't there yet).
One tricky thing about computer and TV displays is that makers will use higher quality panels when they introduce a TV. Then 6 months to a year letter when the model is discounted they will be using an inferior panel that was swapped in (a situation often called a "panel lottery"). You have to be wary of reviews that way because the $1500 TV with glowing review in April wont be quite the same tv selling for $750 in October.
Some computer makers like Dell are famous for pulling the same thing and using outdated motherboards as a model matures. A lot of PCs that end up on HSN, QVC etc are like that. They'll shout about the latest processor (which it will have) but the motherboard will be old (not always bad hardware wise but if the bios is old but you can get crapped if you dont know how to update it). Personally I also dont like the artificially software goosed refresh rates on TVs. That stuff is mostly marketing. In tests people fail to see the difference. I get eye fatigue after a few hours
