What's the best buy for me?

Looking to buy a new TV, no more than $600 here's my situation:

Current 65" Vizio, I hate it

3 windows in room, no real issues with reflection or sun glare.

Almost 1gb wifi speed, current TV is about 5 years old and can't handle the speed.

Tv shows, some movies, and F1 is our usual watching. All via streaming

Can't go bigger than 65" don't wanna go smaller than 55".

Thank you all!
