As I mentioned, each has it's advantages and disadvantages. I think the disadvantages of the LCD are minor compared to it's advantages. However, if I really needed high refresh rates for some obscure reason, I would look for a 30 or 32" 120 or 240Hz LCD with a resolution such as the 30" HP LCD that will do 2560 x 1600.
Input lag comes very apparent when you play fast paced FPS games though. If you don't see it, you don't. When you do, it's annoying.
