G.SKILL Ripjaws X or G.SKILL Sniper Series

[Legassi]

I'm trying upgrade my RAM for my gaming computer. What's the difference between G.SKILL Sniper Series and G.SKILL Ripjaws X? I have a Intel i7 4790k CPU. I am also open to any better RAM for gaming that's ddr 3.

Don't think that for gaming it really matters,but because of the slightly lower timings would i choose the sniper series.
