Since both 120 and 240 are divisible by 24, you won't really notice a difference. It simply makes movie playback smoother since the TV can duplicate each movie frame the exact same amount of times. For instance on a 120hz TV each frame is shown 5 times, whereas on a 60hz screen some frames are 3 times, others only 2 which creates a jitteriness.
When it comes to gaming it's not all that big of a deal, because as we know there is no constant frame rate. It's constantly changing, so in that scenario, you'll be just fine with 60hz.
Save yourself some money and just get the 120hz.
