A lot of good brands. Sony, LG, Samsung. Only brand I personally would not by is TLC. I have a 20+ year old Panasonic plasma I've been wanting to fail so I can buy a new one for the living room.
My latest (1.5 yr old) is a LG oled c2 series. Think the c3 series is the latest. Beautiful picture. Their OS (think it's called LG os) is good. Picture is stellar. Remote control fairly straightforward. So, go oled.
Sony oled has great reviews as well.
PS. Buy from Costco if u can. Great warranty and return policy.
