i like the gigabyte board better because of the usb 3.2 gen 2 port, the extra full size pcie slot and the 2 extra ram slots since more ram is always appreciated in a server.
That said it uses a realtek nic which more than likely will not work without some tinkering for the foreseeable future.
I have a mobo with what i suspect is the same realtek nic (wasn't able to find the model number of the aorus board nic), I cannot use it at all and resorted to using a usb adapter i had on hand instead.
If you can splurge on your 10gb ethernet sooner than later def go for the gigabyte
