What z170 Mobo do I choose??

[Kort Apple]

I'm debating between the

ASRock Z170 Extreme4 ATX Intel Motherboard

& the

ASUS Z170-A ATX Intel Motherboard


Which one is better??

Here is an answer fished from another post.

"They are both very good choices for a motherboard. All things being almost equal I would choose the ASRock Extreme 4:

-Supports a slightly higher top RAM frequency (not a huge deal if you're not a big OC'er)

-More USB 3 ports on the back I/O"
