Armbian for this board is also still under development, since kernel is not matured yet. This is second build and I could not get any of my ath9 / ath10 mPCI wireless cards to work. USB ones should work … Hard to say if it’s any better than stock images. Probably it is, since it’s more recent build and configuration is expanded more, but don’t expect much if any difference at this stage. You are welcome to try out and report your findings. This way things got fixed sooner.
