Odroid C2 vs Rock64?

  • Hi, i need advice for a 4k uhd hdr capable htpc for my dedicated Home theater. But i am confused between the Odroid C2 or Rock64. My only concern is that it should be aptly capable of playing 4k bluray atmos videos or hdr capable movies. i plan to play them via a connected hdd. Please help me decide as to which could be the best device for playing 4k movies thats all.
