50/55" Qled TV under 50k

[nsas02]

I'm currently looking to buy a 50/55" Qled TV with good display under 50k. I can manage with a FTV stick, hence OS is not a problem. Below is what I've shortlisted. I need suggestions from the forum on which one should I go ahead with?

Toshiba M650MP
Toshiba M550MP
Hisense U6K
Hisense E7K/E7K Pro

Usage: Normal TV watching by parents (a decent SD upscaling is needed) and Plex by me. I live is Chennai, hence service shouldn't be a problem with these brands (I hope). None of the offline shops have these TVs on display, I already tried Reliance Digital, Croma, Sathyam, Vasantha & Co.

Open to any suggestions. Currently using Hisense 50A71F for 3.5 years.

How is your older Hisense one doing? Any issues with quality or after sales?
And have you decided your new one yet?

Current one is 3.5 years old. Got a line on my display few days back. Its on the top of the screen, near the panel. So no intrusive. I haven't used Hisense service in these 3 years. So not sure of their service.
Not yet decided on the new one. So many TV models adds to confusion.
