I used a USB AC-wifi dongle on my Odroid-Go Advance, and the performance/latency was about the same as my genuine SteamLink on a gigabit wired connection. The main problem with the Odroid-Go Advance was the screen resolution and size making most UIs unreadable or a chore to use. The screen resolution increase on the Super might help with that though; I plan on getting one once they release, so I guess I'll find out.
