Very similar boards, and really comes down to personal preference/aesthetics
Although:
1. The Gigabyte motherboard supports faster RAM (up to 3866 Mhz vs 3600 on the MSI) - the difference is negligable!
2. Gigabyte board also has 2 LAN ports if that's important to you
3. Gigabyte board has more SATA ports
4. MSI board has an extra PCIe x1 slot

Personally I would go for the Gigabyte board, but it's just down to opinion. (It's also slightly cheaper!)
