Ranked in these QuestionsQuestion Ranking
Pro Software compatible with the Raspberry Pi
ODROID-W is compatible with the Raspberry Pi at least as far as software goes. It can run any software built for the Pi.
Pro Amazing heat dissipation
The ODROID-W has some great heat dissipation. From studying the heat of the heatsink, the maximum temperature registered was 37 degrees Celsius, and that was registered when the board was doing a lot of unpacking through apt-get. Normally the temperature is even lower than that.
Pro Can fit most Pi cases
Since it's built to emulate the Raspberry Pi, it's roughly the same shape albeit a bit smaller. But even then it should be able to fit most Raspberry Pi cases.
Pro USB 3 Bus support
Pro Beats Raspberry Pi on price and performance
Pro Can have up to 4gb of low power RAM
Pro Gigabyte ethernet
Pro 4K/60h hdmi 2a
Pro Barrel power connector
More rugged connection. Less likely to be damaged.
Pro Extra Gpio pins
Pro Main header Pi 3 pin layout
Can use Pi shields.
Con No on-board Ethernet
The ODROID-W has no on-board Ethernet port available, however this can be fixed by using a docking board which has an Ethernet jack.
Con Needs a multi-USB hub
Since it only has a USB host connector available for a full-sized port, you most certainly will need a multi-USB hub to connect more than one external devices to the board.
Con Lack of support, Unstable USB 3,
Only Android with TV UI is available. It is almost unusable with a touchscreen display.
Community is somewhat helpful but is very small. The board developers do not participate in community discussions. No regular Android build available. Lack of accessories and project guidelines.
Con Power connector is not MicroUSB or MiniUSB
Can't use power banks as a power source because of that.
