CRTs are still good, but there are poor quality CRTs just like there are poor quality LCDs. Response time is better with CRTs, you will not see any ghosting. The picture is generally smoother with CRTs, and the blockiness is there with LCDs but you get over it.
LCDs excel in other ways:
-form factor is obvious, they dont eat up your whole desk and they are light.
-brightness is usually better
-geometry is a non-issue (CRTs have pincushion, trapezoid, rotation adjustments that drive you insane)
-with faster response times, I think ghosting is becoming a thing of the past for LCDs
Another thing, you won't see any 'dead pixels' on a CRT. That is an unfortunate side-effect of LCD manufacturing.
My advice is to try them out in a local computer store or borrow a friend's before you buy your own. Most people I think will be happy with LCDs over CRTs for the aforementioned benefits.
So if i got a 17" lcd with 8ms response and connected it via DVI and i ran it at high refresh would i notice bluring that much ?
