The Orange has been a flop to me: lack of support, hard to setup to your needs and overclocked as hell. If you run it at full speed it gets hot enough to burn your finger to the bone.
I cannot speak about the ODROID ones; but the infamous XU4 is well-know by its noisy fan (a big no-no in this kind of devices), my only hope are the C1/C2, specially the later, not being factory overclocked.
