240Hz vs 120Hz if not using 3d?

[SantiagoManager]

If I do not plan to use a 3d feature on the TV, does it matter if I buy a 120Hz or 240Hz? 120Hz are considerably cheaper.

- Plasma tv's have better response times than LCD LED or LCD CCFL, which means less ghosting/lag. 
- Plasma tv's have better refresh rates than LCD LED or LCD CCFL, which means less motion blur. 
= Plasma focused field drives > Plasma sub field drives > LCD 240 hz > LCD 120 hz > LCD 60 hz. 
= Plasma works differently than LCD, but Plasma is better. The higher the refresh rates the better for both 2D and 3D.
