Firestudio vs. audiobox

Hello I have an old Firebox that is still working but sometimes has some digital noise. I am thinking of upgrading my MAC OS...from 10.7 to Sierra. Are both of these units supported? Also with Logic X?

I am conceed about the Audiobox just being USB powered with no firewire cable (unless adapter) and no wall plug

I know the Firestudio would probably be the updated equivalent to what I have now?
