Probably the best thing to do is to go you your nearest dealer/shop/computer superstore and look at both types, especially a TFT if you're used to a CRT.
It's very much a personal thing. Myself, I wouldn't give a TFT a second look, I can't get on with them at all yet some of my staff wouldn't use anything else.
If you do go and have a look , don't just give a casual glance. Spend some time looking at it and, preferably, doing something on a machine fitted with a TFT to see if it suits you.
