Best lga 1151 motherboard between $100-150?

[dantheman0809]

Going to pair an i7 6700k with a motherboard and 16 gb ddr4 2400. Can someone recommend a good motherboard? I've been looking at the z170-a-

I'm planning on overclocking to something like 4.5, and perhaps overclocking the RAM but probably not. I currently only have one gpu, a gtx 970, but I would like the ability to SLI later. Anything better than the z170-a for this price range?

Wait, is that compatible with DDR4? I know in the title it says DDR4, but the only review on that website says it isn't. I'm super confused.

How is it superior to the z170-a? What features? Does it overclock better? I can get the z170-a for $20 less, that's why I'm asking.
