I purchased the Lamobo-R1 and regretted it ever since.
I made myself a promise that I would never purchase anything Lamobo again; it's simply a PCB populated with bugs. It cannot be used as a router+firewall (reason: the WAN and LAN interfacese are BRIDGED by default; that means during startup there's no firewall between your LAN and the WAN, so you're open for attacks).
I've been very tempted to purchase the ExpressoBin, though they advertise a "WAN" port as Ethernet, they just confirmed that it is a Gbit port.
Unfortunately they made the exact same mistake as the BananaPi designers: all the ports are bridged during startup, so the ExpressoBIN can not safely be used as a firewall (attackers, botnets, etc. would have free access to your LAN for as long as it takes the ExpressoBIN to boot up - all it takes is a couple of seconds then your LAN is infected, and imagine what would happen if the router hangs during boot).
The ExpressoBIN is better designed than the BananaPi though - because you can fix the problem by purchasing a Mini-PCIe Ethernet card and use that one for the WAN port. Then you'd still have both SATA free and a USB 3.0 port.
Thus .... it seems that WiTi is probably the very best choice unless going for the MacchiatoBIN.
What I value is true Gbit WAN (and LAN) ports (as many as possible, preferrably 10Gbit if possible for connecting to an uplink port on a switch), a fast CPU (for instance Cortex-A72) with on-chip PCIe and SATA support, multiple 6G SATA ports, a PCIe slot (if possible). As much RAM as possible and preferrably an on-board NAND/eMMC plus an on-board SD-card slot (it should be possible to share one SDIO with both NAND/eMMC and SD by using chip-select; that would mean that access cannot be simultaneous, but that does not matter much to me, as long as installing the operating system can be done using a SD-card; that's the main reason for me to want the SD-card slot.
If PCIe 3.0 is available, Marvell SATA controllers can be used for fast I/O.
I do not care about WiFi at all - I want fast cabled connections.
HDMI would of course be neat, but in my case it's not necessary. I'd be using the WiTi via SSH (and perhaps even as a build-node in my build-farm now and then). HDMI2.0a could of course be used for playing music in the background, as it also transfers audio...
