My parents had a Trinitron when I was a kid; now they have a Samsung Quantum Dot LED display. The Trinitron was nice, but I could spend hours watching videos on the QLED. It's sharper, motion is crisper, and the colors are deep and vibrant.
There's really no comparison in terms of picture quality. And the Samsung is light enough that it can be easily mounted from the ceiling.
There are reasons why the market has shifted to some of these other technologies. Apart from nostalgia and familiarity, you won't miss the Trinitron if you upgrade.
