The Pi 3 is strictly inferior to the ODROID-C2 and Pine64 in the areas he cares about - less RAM, slower I/O, proprietary bootloader that can't even boot 64-bit

The Pi 3 is strictly inferior to the ODROID-C2 and Pine64 in the areas he cares about - less RAM, slower I/O, proprietary bootloader that can't even boot 64-bit kernels, etc. Plus it still doesn't use a standard PC form factor. It's not even cheaper either.
