I can contribute only two observations from my (little) experience: 1) I have two Banana Pis. One is running 24/7 for almost 2 years now. I reboot it once a week and whenever the kernel gets updated (in the beginning I used the old 3.4 kernels, and since 4.0 I use mainline, currently the longterm version 4.4). Aside from an issue I had with the first power adaptor I used in the first weeks after purchasing the device (see 2) below), this has been running absolutely stable ever since and never let me down. 2) You are right about the power source. The first USB power adaptor I used with my Banana Pi was faulty. It would run fine for some time, but after a few hours or days the voltage would suddenly drop which would turn off the device and shortly after, the power would come back and the Banana Pi would boot up again. I returned the power supply to the dealer and go a different one which ever since runs fine. For my second Banana Pi I used an old 2A rated USB power supply that came with an ASUS tablet and with that I also haven't had any issues. Now, which devices would I recommend? Well, I'm happy with my Banana Pis, they work really well and were super cheap. In terms of board design however, I find the A20 Olixuino Lime2 more convincing, simply because it comes with a more reliable barrel plug for power supply and you can even get it with eMMC storage now. I never bought one, though, because at the time I got my first Banana Pi, the Lime2 wasn't available yet and in the meantime I saw now need to replace it.
