CRTs basically have better image quality to LCDs. LCDs are limited to their native resolution, which tends to be rather low. For example your average 19" LCD tends to have a native res of 1280*1024, which is quite low for that screen size, leading to a rather pixelated looking image. Many 19" CRTs can go up to 1600*1400 and more, and still maintain a decent refresh rate. To achieve such a resolution on a CRT you'd need at least a 20" screen - but this is basically, more or less, increasing the screen size to add those extra pixels and not increasing the pitch.
