We have gone through a lot of TVs recently with kids moving to college, kids moving out, donating an old TV to my in-laws, and getting two new ones for the home. We have used Vizio, Sony, Samsung, and LG. The only one we had any trouble with hooking up to the internet was an older Vizio Smartcast. It went to my daughter's new apartment. She had WiFi but for some reason it wouldn't connect. We even tried an ethernet connection. My son worked with it for about 3 hours and finally it just connected. We don't know why it took that long or why it had problems. It is working well for my daughter though. Since the other three have had no problems in the Smart TV area, I would rate them as far as picture 1. Sony, 2. LG, and 3. Samsung. The Sony is their top of the line since I didn't want to wait on the new LG OLED (actually, I didn't want to pay $1500 for the size I needed). I bought an LG UHD for our bedroom and it was under $300. For the money, it has a great picture. So, I kind of wish I had bought the larger LG for the Living Room since the smaller one had such a good picture considering the price.
