I have mixed feelings about this. If you zoom in, it looks especially bad. If you are talking about consoles that had like 320x240 pixel resolutions, it is especially bad, but a high resolution LCD display can use filters/shaders (whatever you want to call them) to mitigate the blockiness to a large degree. Early LCDs were simply no match for a good CRT. I would argue with people all the time and they simply couldn’t believe it and thought I was crazy. But now that we have LCDs with more than 4K resolution it is game over for CRTs and my back hurts just thinking about moving another 100 lb vacuum tube monitor.
