Tv purchasing advice

I’m looking to buy a tv. I walked around luthuli avenue hoping to get some insight but i ended up even more confused, there were so many brands. Later on in the day, i came across what i thought was a great deal, a syinix smart tv retailing for 18,000 and a hisense smart tv retailing for 500 more. Long story short, I’ve decided to turn to the tech community for advice on better deals (if any), and how to tell whether a product is genuine
Ps. My budget is anything below 20k
