Well, when Tinkerboard, then there is no reason to take the old one, Tinkerboard S would be the best choice.
It would offer you to boot from emmc or sd.
Mini86, as part of many other x86 platform options, is a good and very stable alternative.
Note, Khadas VIM3L is too new and there is no build for it yet.
But the board looks very promising and we plan to work on it as soon as hardware arrives.
