They both should be CAS 9, so the Corsair would be "faster" of the two. Going off Amazon pricing, there is a 20$ difference. Personally, I don't think you'll notice a difference in performance, so I would get what fits your budget best, or what fits any sort of color scheme you may have for your build. If it's crucial you have the fastest for work projects, then go ahead and spend the extra 20 and grab the Corsair.
