Cryptonote powers usage is not accurate. It should draw power less against ethash. It's use the lowest power for those three of that algo.
My rig (Voltage offset @ -15)
ETH (27*5) Power usage 660W-670W
XMR (700*5) Power usage 460-470W

Looks like XMR is your winner, but ETH isn't too far behind
In my personal experience at the end of the day (coins on exchange or personal wallet) you will get more with ETH, even though sometimes the calculator says that you should mine XMR.
