Samsung 60 Hz or LG 120 Hz? Is samsung better to justify the lower Hz (used for gamin

I don't know much about tvs but i'm deciding between these two;

Samsung 46" 1080p 60Hz LED HDTV (UN46EH5000) for 577

or

LG 47" 1080p 120Hz LED HDTV (47LS4500) for 647

Are LGs comparable to Samsung, would Samsung with lower Hz perform better?
