Enough for simple tasks Raspberry Pi 3

I prefer to stick to RPi as it has far superior software support than many other similar alternatives. There are more powerful and more feature rich products already available on the market, however they are often hard just to get them to work because the software support is still lacking.

Another important thing that makes Raspberry Pi more attractive is the really good price/performance ratio it offers. Usually slightly more powerful or with just a few extra features boards may cost twice or even more compared to a RPi.

So RPi 3 is still the best choice for me personally and I have been using RPi since the fist model came out... :)

I used the Raspberry Pi to load Kodi on back when Kodi was called XBMC, it worked well. Then I used the B and the B+, they worked better but no wifi.  Mind you I use these as streaming platforms with Kodi as the OS. The problem across the board with the RapbPi models is they are limited to 1gb of ram, so no bells and whistles for you. The issue with ALL the boards is you have to have a SD or Mini SD card, a flash drive if you want optimal stability, and you have to get a case and heat sinks if you want optimal performance. This is why I gave them all up and went with a Matricom G Box Q2, on which I can install Kodi with ALL the bells and whistles because the one I use has 2 gigs of DDR3 ram, 16gb of onboard storage with an SD slot upgradeable to 64gb and a Amlogic s812 Quad Core processor running at 2ghz along with a Mali-450 Octo Core 3D GPU. All this for under $100. That aside if I had to choose from the chart above, I would hands down go with the ODroid C2.

Not for nodes but I use several RPis for my 3d printing and a few other things, just playing with a Pine64 running a a full computer.... very impressed so far :)
