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 6 core HexaCore, compact nvme extender, 4GB RAM
Pro Many ports
4 x USB3
2 x USB2 available via pins
PCI-E available via pins
Rockchip 3399 with two fast A72 cores. Good heatsink limites throttling.
Pro Open Source
Works with mainline Linux kernel and open source Mesa Panfrost drivers.
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 Bleeding edge...
To have mainline kernel requires a bit of tinkering (e.g. installing Armbian). Panfrost drivers for 3d acceleration are not mature and crash sometimes...
