You can actually visit any of the offline stores to compare. I had actually ordered it to one of my cousins and the display was top notch. Also, the processor is quite fast and Google assistant works flawlessly. (Assistant was a major issue with Xiaomi, TCL etc where I simply couldn't voice search anything).There are no issues even with the Chromecast (again, found casting issues in Xiaomi and TCL).
You get 50"inch for around 46k with bank and card discounts. It's available both on Amazon and Flipkart sites.
My best suggestion would be to physically compare the display qualities of the above mentioned TV models and come to conclusion.
