Best board for PSP emulation

I wanted to get everyone’s opinion on the best board available for PSP emulation. Odroid has released the C2 and XU4 and the PI3 is now available .

Lakka has a hardware support link (http://www.lakka.tv/doc/Hardware-support/), but it has not been updated recently. Any thoughts?

Note: PSP and PSX emulation are my main concern.
