The more important spec would be, what CPU are you using? Then if you say anything other than an i7 8xx, the question is whether you are going to overclock or like to play with RAM BIOS settings.
If you don't plan to overclock the RAM and do NOT have an i7, then you will not be able to run at 1600MHz. In which case get 1333 - unless there is 1600 that is the same price or cheaper, or has tighter timings (for the same price or cheaper). Just be prepared to run that 1600 rated RAM at 1333 MHz. There is very little performance difference between 1333 MHz and 1600 MHz. Check out the RAM articles on this site for evidence of this.
I've got the same board. See my sig for CPU & RAM. The same RAM almost a year ago was about $20 cheaper than it is today (or last time I looked), so it's not necessarily what I'd get now but it does work as expected, never had a problem. The low V RAM looks interesting. It was not an option when I put my rig together.
