While CRTs are fading into the past in most people's minds, they can still go toe to toe with modern displays when deliberating on the proper screen type to purchase.
Cost
CRTs are based on older technology and are undergoing a steady decrease in demand, so they will be cheaper than a LCD with similar specs.
Display Quality
Both LCDs and CRTs can achieve high-definition resolutions or better. Because of rounding caused by the CRT's design, LCDs create a sharper image when working on their native resolution, but CRTs are more flexible with their aspect ratios and resolutions. The brilliant crystals of the LCD are capable of much more brightness than a CRT, but the other can produce a broader range of gray and darker images that are better suited for dim rooms.
Power Consumption
LCDs take less than half as much energy to run when compared to CRTs of a similar size. Large CRT models designed for shared spaces can easily draw over 250 Watts; If you use the television for a full day, it can use as much energy as an AC running during the day. You'll be able to feel the power draw in the heat emanating from your CRT after a couple hours of use.
Size and Configuration
The size and shape of a CRT is typically the main method used to tell them apart from LCDs. The tubes and equipment surrounding them fill up the bulky back section of a CRT, making them impractical for wall mounting and usually twice as heavy as a naturally flat LCD monitor.
Lifespan
Both LCDs and CRTs can live for decades with most units surviving without incident for at least five years. CRTs slowly lose image focus over time, whereas LCDs remain bright but suffer from effective screen size loss from dead pixels.
