I have bought USB3 dongles with ASIX AX88179 and Realtek RTL8153 chipsets. Both work right out of the box on Coreelec/Libreelec/OSMC etc. with no requirement to install any drivers.
I found i was getting better and more consisstent performance form the Realtek dongle when connected to a USB 2 port.
On there internet there are may who recomend the AX88179 dongles due to compatibltiy with nintendo switch etc. If you have a choice, I would recomend the Realtek for Linux based applications.
