CRTs have a few advantages, they look good at any resolution where most LCDs have issues at non-native resolutions, the good ones also have image quality at least as good as the best LCDs. But they take up a ton of room and use up more energy, and the older ones tend to have image ghosting, brightness and convergance issues.
If that monitor is in good shape, it will look great. Mitsubishi CRTs were very good quality, if you don't care about the size/power thing, and the screen is not bad due to age, you'll be happy with the image.
