Ahhhh, I still have great memories of our family's 27" Trinitron XBR. That was a fantastic beast. Panasonic and JVC also had some really good CRTs back in those days.
I still have a ~20 year old Samsung LCD that is going strong as a secondary TV and the Panasonic Plasma I got for my parents around 15 years ago is incredible and I'm still a bit jealous I don't have one.
These days, I've been impressed with the quality of picture and low prices I've seen for TVs but I can't bring myself to go with anything but LG OLEDs. The quality is getting to the point where it's like DACs that someone else mentioned earlier and you can get a really good picture for very little money. But since I buy things and keep them around as long as possible, it's worth it to me to pay a little extra to know I'm using the same panels that are widely used, developed with and adopted by many in the M&E industry.
