Gigabyte GA-Z77X-UD5H, Z77 vs. MSI Z77A-GD65, Z77

I want to build an audio editing pc and I can't decide which motherboard is better for me. I just thought, it was the gigabyte, but then Logan once used the MSI, and I thought "this isn't bad as well". Which one is better for overclocking and which one supports faster memory?

Another question, that might be importaint is if USB3's speed is comparable to eSATA'S in terms of external hard drives.

To make it easier for you, this link leads you to a comparison of the two boards:
