Rpi with signature or sparky with usb bridge or just a asus tinkerboard

Hello guys.

Again lets talk for end point. I have the rpi 3 b+ with ropiee. I want and upgrade.

I will buy lps 1.2…but now i am in big dilemma.

Having a ifi iusb nano and thinking to buy also a igalvanic. But i don’t if the signature kills the iusb + igalvanic +tinkerboard or rspb/sparky with usb bridge.

After that i don’t know if the usb bridge is only for sparky and which is the best of 3 options. Asus is as sparky it doen’t share ethernet and usb.

Any ideas?
