I can't vouch for it being the best, but when I was looking for the same thing I ended up with the ASRock FM2A88X-ITX+. Can't say I've been let down in the least with it. My biggest concern when selecting it versus the comparable MSI and Gigabyte offerings was it's lack of heatsinks on the VRMs, turned out that was a non issue, it's had no issue handling my 7850K all the way up to 4.7GHz. It's other knock compared to those two is they have wireless-ac, it only has wireless-n. As for it's advantages, it has more SATA ports, HDMI-in pass-through, e-SATA, as well as more motherboard USB headers.
