Yes they are...there is a massive differenceLG is best, followed by Samsung, but if you don't want TV over the air, just get yourself a firestick.
I've got a 10 year old 55" TV which has a smarthub that is so out of date, nothing works. I've added a firestick and I've no got everything I need.
Are they really that much different from the 55" ones selling for £500? Unless you've got perfect eyesight and sit close, you'll not notice the difference.
