if you game for money, or are involved in serious FPS tournaments, then go with a CRT or if you've tested X LCD and ghosting doesn't bother you, or you don't notice it, then I'd still go with the tried and true CRT for really serious FPS gaming where you want any possible advantage you can get, otherwise get an LCD and force it to 75hz (if manual says its ok) for gaming.
also note that LCDs use less electricity (my 1905fp (dell) states 32 watts without the soundbar and usb). this can really add up if you have the monitor running a lot.
