I honestly don think you can say your Samsung is better than the Vizio. Though you dont say what model. If I had to choose I would be biased to Samsung for sure.
All the manufacturers have base models, then mid level to high end. I guess if you go to the manufacturers site and look up what you may have a better idea.
BTW - QLED a "trademark" of a commonly used LED panel. Just because someone may not use the word QLED the technology is the same, Sony invented it.
The stand out technology depending on if you want it is the one and only LG OLED which is truly different and now used by other companies.
SO there is LGs OLED panels and there is everything else that is the same.
